I had unprotected sex the first night I missed my pill. The other two nights I didn't. I then started bleeding today.. Like a really heavy period even though I got my period two weeks ago. This will be the start of my second week on my new pack. I'm not going to be upset if i'm pregnant I just want to know my chances. If there are any since I already started bleeding. Or is that just what the call a "pill period" Please someone tell me soon.. I want to know before my boyfriend goes to college and we plan our life out.
