Ok, 3 weeks ago I had very ba cramping at a time when I should've gotten my period, the cramping lasted a week but I never got my period. A week went by with nothing, I gad mild crampin and alit of discharge. I took 2 pregnancy tests, they were both negative (taken a few days apart both with first mornings urine). 4 days ago I started bleeding off and on very light then very heavy. Then it stops and starts. I've noticed what I think is blood clots. Quite a few small ones and one rather large one 2 nights ago. I can't get to my OB, I have to take medical transport and I've already used all my rides for the year because of my pregnancy (gave birth. 6 months ago). My question is could I have been pregnant and had a miscarriage?
