So I have always taken the depp shot and it worked very well but made me gain extreme weight! So I wanted to try the birth control pills. My doctor prescribed them for me and I am not really sure when to start taking them. I started my period 3 days ago was I supposed to take them when my period started? Or can I take them when my period ends? my period is almost over can I take it when it's over? Help I'm sorry I know this is a dumb question but I've never had to use the pills.
