My friend thinks she might be pregnant cuz she hasn't had her period yet. is there any kind of pill to take now to be safe or is it to late?

Prenatal vitamins: Too late? For what? Prenatal vitamins are a good idea when pregnant although once pregnant, they're not as good for lowering risk of neural tube defects. If you're asking about a morning after pill, then way too late. Abortion pill? She'll need to see a doc. Better yet, get her a home pregnancy test which are incredibly accurate after missing period. Then base questions on result, not guess.

Depends: On when her period is due and when she had sex. I would see your doctor or pharmacist to see if you are in the window period.
