Okay so long story short, i was trying to concieve for a while. yeah and then i stopped trying. however, the week that i knew my period was coming, i had unprotected sex. He nutted in me but we didnt think much of it. I immediately however had tinderness in my breast. It was that monday but then that friday my period came on. Started put very light for two days then was heavy the third day and went down until it was only spotting on tuesday. Four days after my period went off i checked my underwear that night after having light cramps and there was one line of brown blood. i checked and nothing was there. the next day there was a little bit of brown blood that night too. then yesterday i bleed another little bit of brown blood again. ive have light cramping barely and nausea. I have always heard that implanation comes before a period but since th s conception would be RIGHT before my period, is it possible that this is implanation bleeding and i am pregnant??
