I thought I may have goten pregnant and me and my boyfriend had sex yesturday and when he puled out there was blood and so I put on a tampon and when I pulled it out an hour later to shower there was almost no blood just spots that were a pinkish color and if it qas my period there would have been a lot. My period comes very hevily andits really not scheduled until next week. But then today (may 2, 2012 and 7dpo) there was no blood or anything could that have been implantaion bleeding?
