I stopped taking birth control pills for about 4months now && since then I haven't had my period should I be worried?
By the time you're 4 months or even 3 months pregnant you would know...however you may need to talk to your doctor about getting your period back...its not healthy to not have one unless you're pregnant.
Go see your doctor, you shouldn't be that long without a period after coming off birth control pills. You could possibly be pregnant.
I wouldn't worry. Eat healthy, don't drink take a home pregnancy test and see what it says.
