There is, arguably, more superstition surrounding pregnancy than any other so-called "medical condition." To separate fact from fiction, we examined the science behind the hearsay.

"Pregnancy brain" makes it impossible to concentrate.

This may be true in the first few months, when a 30-fold increase in progesterone makes most women really, really, sleepy. And some researchers say pregnancy hormones may make it hard for a pregnant woman to remember where she placed her keys.

But pregnancy brain may not be all bad.

In a small pilot study of 10 women, Stone and colleagues found that women tend to have increased attention spans in their third trimester. If the results are confirmed in a larger group of women — something the researchers are currently working on — it may be an indicator of "neuronal nesting."

"This may be nature's way of increasing the attention a mother is going to need to give a newborn," Stone said.

"Morning" sickness only happens in the morning.

If only this were true! Thought to be caused by shifting hormones, morning sickness can strike (and often does) at any point in the day.

And it's not confined to the first trimester, as many believe, Stone said. "It can last up to 16 weeks."

Drinking any alcohol during pregnancy will hurt your baby.

While binge drinking during pregnancy can cause severe problems, recent studies of thousands of women in the United Kingdom and Australia have confirmed earlier research suggesting that light to moderate drinking – usually defined as one drink a week to one small drink most days – may not be harmful.

Drinking during pregnancy is more culturally acceptable in Europe and Australia, where pregnant woman imbibe more openly than in the United States. But many physicians in the United States, such as Dr. Michael Broder, author of "Panic-Free Pregnancy" (Perigee Trade, 2004), also quietly allow their patients to have the occasional alcoholic drink – particularly after the first trimester.

Pregnancy makes your feet grow.

While most women experience some swelling in their calves, ankles and feet during pregnancy, many can fit back into their favorite heels at some point postpartum.

But this one isn't a complete myth: Some women permanently go up a half-size over the course of a pregnancy – and possibly even another half-size with each subsequent pregnancy.

"Hopefully, they're not having ten kids," Stone laughed.

Your body shape will never be the same again.

"With exercise and diet, it certainly is possible to get back in the shape you were in before getting pregnant," Stone said, adding that this is easiest for people who were quite fit before conceiving.

People tend to forget that the body changes with age, with or without a pregnancy, Stone told MyHealthNewsDaily. So before blaming your saddlebags on your offspring, try counting the candles on your next birthday cake.

The mom-to-be is the only one going through hormonal changes.

She's not alone: Dad's dealing with hormone shifts, too.

A study published in the journal Evolution and Human Behavior in 2000 found that over the course of his mate's pregnancy, an expectant father's testosterone levels go down and his prolactin levels go up. Researchers think this adjustment may help prime dudes to play daddy.

Breastfeeding makes your breasts sag.

While infants certainly drain a lactating breast, their hunger doesn't cause long-term changes in breast firmness. Scientists have confirmed breastfeeding does not contribute to breast ptosis (the scientific name for saggy breasts).

However, multiple pregnancies, smoking and simply getting older have been correlated with droopier cleavage, according to a study of 132 women published in the Annals of Plastic Surgery in May.

Twins skip a generation.

Fraternal twins do run in families, due to a gene that can make a woman more likely to release multiple eggs during ovulation. But the hyper-ovulation gene doesn't leapfrog over certain generations. It is passed on from parent to child just like all genes are.

Evidence shows that identical twins, however, occur at random, rather than running in families. If there are many sets of carbon-copies in your family line, "it is probably just a coincidence," Vreeman told My Health News Daily.

You can predict the sex of your baby without technology.

Time to break it to grandma: Basketball-shaped bellies do not forecast boys. In a study of 104 women, published in the journal Birth in 1999, no correlations were found between a pregnant belly's size or shape and the baby's gender.

Similarly, predictions using the Chinese lunar calendar, the fetal heart rate and the Drano test (where the woman's urine is mixed with the de-clogging liquid and the resulting color allegedly reveals the baby's gender) were examined by physicians in Vancouver in 1999. None of them were reliable.

Neither is women's intuition dependably accurate, according to a 1996 article in the Journal of Reproductive Medicine. Of 110 women who professed having a strong sense of the baby's gender, roughly half were right – the same number expected to be right if they were just guessing.

In all, scientists have found most folklore-based methods of predicting a baby's sex have the same odds as flipping a coin. "And 50/50 odds are not that bad," Vreeman said.

There may be a case for the predictive value of extreme morning sickness. Excessive, unrelenting morning sickness – also known as hyperemesis gravidarum – is slightly more correlated with having girls, Vreeman said.

When you have sex determines the gender of your baby.

Dads-to-be have two types of sperm: those that make baby boys and those that make baby girls. Some say that the body of a mom-to-be is more hospitable to boy sperm or girl sperm during certain times in her cycle. And so, the theories go, when a couple has sex can determine whether they conceive a Junior or a Bubette.

While a few small studies have supported timing methods for sex selection, larger, more recent studies have failed to find any correlation between the day within the fertile window a couple has sex and the gender of the baby, explained Dr. Rachel Vreeman, co-author of "Don't Swallow Your Gum! Myths, Half-Truths, and Outright Lies about Your Body and Health" (St. Martin's Griffin, 2009).

The only way you can reliably choose the sex of your baby is with the help of technology

Pregnancy lasts nine months.

"It's actually more like nine-and-a-half months," said Dr. Joanne Stone, an obstetrician at Mount Sinai School of Medicine in New York City and co-author of "Pregnancy for Dummies" (For Dummies, 2009).

To make matters more confusing, doctors typically measure pregnancy's length as 40 weeks, counting from a woman's last period. Women usually become fertile 10 to 16 days after their period starts, so from this method of counting, the first two weeks of every pregnancy take place before a woman has conceived.

You just might get the idea that I am a soon to be Grand mother and you would be correct.

The biggest myth I encounter is that people think if they have a kid everything will eventually work out.
This is not true:
If a relationship is in trouble getting pregnant will not make it better.
If you have financial problems having a baby does not help that either.

Most people plan very poorly before they get pregnant, they assume that "wanting" a baby is the same as being ready for one!

Hmmm. So I need to get pregnant to be able to sleep again? And to excuse my senior moments? Oh my, the situation is more dire than I thought. Now why can't some enterprising pharma company synthesize this sleeping pill, and borrow a bit of that neuronal stuff so I can find my keys?

So true Gene, I have chronic insomnia, though not while I was pregnant. I slept so well, continuing my running routines and worked till the day before delivery. I never had one day of morning sickness, and I had carefully planned to have enough money set side that being at home was in no way a stress for our way of life.

Brenda is correct, pregnancy and children do not, can not save a broken marriage, they do add stress, financial pressures, and can add marital conflict.

Good article. We also need to keep reminding doctors and the public that pregnancy is natural: it is NOT a pathological condition.

That is so true Brian. I was again reminded of this as my son and his wife are beginning this grand adventure. Rather than tolerate the nonsense of hospitals and artificial treatments, I was able to use a mid-wife clinic. My daughter in law is doing the same. She has already contracted with a doula and a back up hospital should that by some rare chance be needed.

I agree with Brian M - above. I was blessed to have 3 wonderful pregnancies and three healthy boys as a result. But it is not something you can take for granted. Such is the way of life ...

Aww mom and Congratulations Kit. Your Daughter or Daughter in - law? and Goddess Blessings for the new arrival. Aliyah was healthy, I had complications because I tore the placenta at 24 weeks from an accident I was involved in which caused an infection. Soooo needless to say, split and tore an upper hole. Bed rest and anti-biotics and ongoing troubles. But, panic'y mom and hen pecked could not get away with anything. :( Now everything is healing well. Wishing you many happy moons and smiles :) my crazy mom can shut up and get some sleep. hahaha!

Krystal, I am so sorry you had such a rough time with your pregnancy. I hope you heal fast that new little one will not give you much time for rest. It is my son and his wife that will be giving me my first grand child, due in mid-April. Congratulations to both Krystal and Roxy for the new arrival.
