I stopped birth control after me and my bf split, and now I am restarting it. Will I have a period right away as soon as I take it... and also, me and my ex had sex and I had taken plan b right before that, am I safe from not being pregnant?
Plan B is not 100% guaranteed to work. It's less reliable than birth control. You need to do a pregnancy test when enough time has lapsed, to see if you are pregnant.
Plan B can knock your periods out of cycle for weeks, sometimes months. It's impossible to say when you'll get a period.
