Okay, so I had my period July 13th-19th. On my second fertile window day, I had unprotected sex. He pulled out, but I'm 35 and I know that he easily could have ejaculated a little beforehand. So, fast forward to this week. I started spotting this past Wednesday, It was brownish. Now I have a light, but steady period. My period wasn't due to start for two weeks. Has anyone ever experienced this and not ended up pregnant?

A little extra info:

I don't believe in abortion for myself, so if I am pregnant, my child will have a British father (who still lives near London) who is ten years younger. We met while on vacation. I have two children with my ex already. Life would be crazy, but the possible father and I definitely have a connection. We've spoken every day since we met. He's a romantic just like me.
