Ok so I was 14 days late on my period which has never happened to me (except for when I was pregnant) and then When I finally did start it was only 3 days long and lite. Normally it lasts for 6-7 days and is heavy! Then 3 days after I ended I was washing bottles (I have a 5 mo old) and a gush of dark brown blood came out and that was it- it didn't keep going or anything. And on top of it all I keep having sharp pains below my belly button on the right. I did visit the Dr. before I started and he said it could be a cyst causing pain then did an exam and said there is nothing there. He didn't think I should be concerned. And I couldn't be pregnant because my husband had a vasectomy about 10 or 11 months ago. Plus I took 2 tests on my own just to be sure and of course the Dr. ordered a blood test just to rule it out- even though the pee test at his office was neg too. So any idea what could be going on??
