Pill ?

Hi ? and hoping for a solution!

I been on a new birth control for 3 weeks and on 4th week was suppose to have period. Well its been 4 days and no period! Should I worry or take a wait and see approach?

Thank you and have a great weekend All!

Actually, it's pretty common for your period to be off-schedule for a couple of months after starting birth control (in fact, up to 3 months). That is how long it takes for the drug to get into your system, which is why the literature that comes with your birth control advises the use of alternative birth control (e.g. condoms) for the first three months after beginning the pill, and for any time after missing a pill. If you miss more than one period (and you don't have any spotting between the placebo pills), you should probably let your OB-GYN know, just to be sure.

And don't worry, there is no proof that the pill (or some IUDs, though not all of them) causes harm to a growing baby.
