So I a week and a half to two weeks ago I had what I thought was implantation bleeding, very light, lasted only a day, was having a few pregnancy symptoms took a test and it was a BFN.. I ended up starting my period, but (again TMI) it has been the heaviest period I've had since sixth grade. I literally stood up and blood poured into a puddle on the floor and there are a lot of clots which I've never had during a period. Could periods change due to different hormones while TTC? This is a very new adventure for me, this is literally the first month trying, but this period freaked me out a little. Has anyone experienced this before?
