I normally have a very heavy period and I did just two weeks ago. But starting yesterday I have been having very light bleeding. It started with just a little pink on the toilet paper. Then it was brown. And now I am bleeding a little more but still no clots or anything like the normal when I'm on my period. I'm on the pill but I stopped taking them yesterday because I'm worried I could be pregnant. Is it possible this could be implantation bleeding? I've been having symptoms which everyone says is impossible at the stage I would be at. And a pregnancy test said negative()but maybe it's too soon to tell?. Last week I was sick and was having a hard time eating anything. Then that finally went away(figured out frequent small meals helped) but then I had back pain, frequent headaches, and my belly's been itchy? Not really sure if the itchy belly is a symptom or not but it's been driving me nuts. I'm also totally exhausted(I slept 12 hours one night and was still tired the next day). At some points the cramping has gotten just as bad as when I'm on my period but still no clots and no heavy bleeding like my period. I'm just a little thrown off as I was positive I was pregnant, because I've thought I was before but nothing has EVER been like this. I was positive that I was yesterday until the cramps got as bad as they are on my period. Now I'm just wondering what is up...the bleeding seems watered down and its reddish brown in color.
