My boyfriend and I had unprotected sex on Dec. 17. My period was supposed to start on the 19th. I took the morning after pill on the 18th and I got my period on the 21st and didn't end until the 27th . Then we had sex on January 1st unprotected, but he did pull out. A few days later, I noticed I was spotting and that lasted for a day or two. I was wondering if there is a chance I am pregnant. I also took 2 pregnancy tests and both came out negative. Please help!
