Here's the story so my boyfriend and I have sex and I believe it was on the 27th of Dec or the saturday before that that we had sex and he cummed into me and after that we had it 3 days straight and I let him just go ahead and cum in me. I skipped the whole month of December of not getting my period. and I finally got my period on January 2nd 2010 and like it completely ended on the 5th it was seemed like a heavy flow but then; so it stopped completely on the 5th that night I went to bed wearing a pad just in case my period had not stopped but in the morning when I checked it there was absolutely no blood so I thought "yay no blood I'm off my period" but then yesterday I was in a class like around 10:05am I felt like I bled or something so I went to the bathroom and checked and I saw some blood but it was very light I thought oh hmm maybe i just got my period again so I stuck in a tampon then once again last night it completely stoped and I thought ok now Im done with my period for sure but today around lunch time and whatever and when I went to the bathroom there was some blood on my panties, but the blood drops were like spots and I had some really short lines of blood but the blood drops were like small circles. Is it possible that I had implantation bleeding and now I'm spotting? Does this mean there is a higher chance of me being pregnant??
