Whenever I ask for help on here no one ever helps me but I'll ask anyways.

On Monday Feb 20th me and my boyfriend had unprotected sex. He pulled out and said he didn't come in me and I watched him cum on my stomach though there was definitely some white stuff near and in my vagina.

I was supposed to get my period on Thursday Feb 23rd and it still hasn't come yet. We talked about plan b but decided not to take it and to keep waiting.

Throughout my most recent cycle though I had mid cycle bleeding. Which is very unusual for me. That was for 4 days from Feb 5th-8th. Is that what's making my period late or could I possibly be pregnant? Please help it's really stressing the both of us out. We are only 19 and in no position to have a baby. We would have to abort it.

Edit: we always use protection. We have been together for an entire year and have used birth control every single time. Last Monday was the only day that we wanted to try without anything in between us.
