There's a lot of misinformation out there. Here are the facts about pregnancy, debunking the most common myths.
Myth
You can't get pregnant the first time you have sex.
Truth
You can get pregnant any time you have unprotected sex, including the very first time. Ovulation doesn't wait for experience.
Myth
You can't get pregnant on your period.
Truth
While it's less likely, it is possible -- especially if you have shorter or irregular cycles. Sperm can survive in the body for up to five days.
Myth
Pulling out prevents pregnancy.
Truth
Pre-ejaculate (pre-cum) can contain sperm. The withdrawal method is not a reliable form of contraception, with a typical-use failure rate of about 20%.
Myth
Birth control is 100% effective.
Truth
No method of birth control is 100% effective. Even with perfect use, most methods have a small failure rate. Typical use failure rates are even higher.
Myth
You'll know right away if you're pregnant.
Truth
Many women don't notice symptoms for several weeks. Some women have very mild symptoms that are easy to overlook or mistake for something else.
Myth
Morning sickness only happens in the morning.
Truth
Despite the name, pregnancy-related nausea can strike at any time of day or night. For some women, it lasts all day.
Myth
Stress causes miscarriage.
Truth
Most miscarriages are caused by chromosomal abnormalities that occur by chance. While extreme stress isn't ideal, everyday stress does not cause miscarriage.
Myth
You should eat for two when pregnant.
Truth
You only need about 300 extra calories per day during pregnancy. Focus on nutrient-rich foods rather than doubling your portions.
