Okay, so I am almost two weeks late. I got my birth control out (implant) October 7th and a few days after removal had a normal 4 day period. Regular flow, and everything was normal. But since that period I have not had one. It's been almost two weeks since I was suppose to start it. I have had unprotected sex several times but he pulled out (which I understand does not always make a difference). I took a pregnancy test last week and it came back negative. So I was wondering if any of you know what the chances of me possibly being pregnant are. All responses would be greatly appreciated!
