This morning I woke up and when I went to use the bathroom I noticed some pink blood in the toilet like maybe a few drops and when I wiped it was just light pink, throughout the day I wore a panty liner but it was so light it didn't even get on it. By supper it stopped and now I just have very watery brown discharge (sorry tmi) and barely enough to get on a panty liner. I'm 4 days early for my period and there is very much potential that I could be pregnant as we had a bit of a whoopsie during this cycle. My periods are usually extremely heavy and crampy yet all I had was some cramping this afternoon and nothing now. Does this sound like implantation bleeding?
