"I am 5 weeks pregnant and everyone thinks I'm showing, but I have to keep telling them I'm just bloated!" - jessicadelynn

What it feels like: Irregular (or nonexistent) bowel movements and a gassy, backed-up feeling in your abdomen.

What causes it: Hormones slow down your digestive system. Some prenatal vitamins and medications can cause constipation and gas, too.

When it starts and ends: Constipation and bloating often start in month 2 and can last throughout pregnancy.

What to do about it: Drink lots of water. Keep moving. Eat plenty of fiber-rich foods. Try smaller, more frequent meals.

"I've taken a probiotic and a fiber supplement for most of my pregnancy. Make sure you're staying hydrated and eating your greens." - LazZzyBones

When to talk to the doctor: If you've been backed up for days or you're experiencing pain, ask your doctor about pregnancy-safe remedies.
