If I had unprotected sex and had my period a week later, does that mean I’m not pregnant?
Yes. Getting your period means you’re not pregnant.
In the future, using a regular form of birth control — like the IUD, pill, or shot — whenever you have sex is the best way to help prevent pregnancy. And using a condom in addition to another form of birth control every time you have sex gives you extra protection from pregnancy and also protects you and your partner from STDs.
