I’ve been on birth control for probably three years, and I make sure I take it on a schedule. I was supposed to start my period last Sunday, the 19th. Me and my boyfriend had unprotected sex on the 17th. I’ve been having symptoms of pregnancy and what I think to be implantation bleeding. On Thursday I started to have a very very light pink (which I usually start with brown old blood) the. It stopped until Saturday night which was a light creamy brown discharge color. I went to test today but it seems like I started my period and I’m supposed to start my new month of birth control tonight. Can you just start your period a week late like this or do I have a chance of being pregnant?

Update: I’m not bleeding anymore, the period looking stuff lasted a few hours and now there’s nothing
