Here's my deal...I don't even know if I was pregnant first of all but had a few symptoms (breast swelling/tenderness, lump in abdomen, exhaustion, etc.). Well I just started my period a week early and this morning had the worst cramps of my life to where I could do nothing but curl up in a ball in bed and cry. I've had cramping all day today, sometimes a lot worse than other times but also have been bleeding heavily and passing a lot of dark red/brownish tissue/blood clots. Could I have been pregnant? And could I be miscarrying? Any help would be REALLY appreciated. I've never had a period like this before.
