Hello, I may be making a mountain out of a molehill, but I'm having the worst period I've ever had by far. A couple of day early, which doesn't usually happen, extreme cramping, and lots of clots and thick strings, which I don't normally notice. Very heavy bleeding also, and bad back pain. Anyway, it's only after a few days of this unusual bleeding, that I thought maybe it was a miscarriage of some sort? I had a suspicion I may be pregnant, but as my period wasn't due, I didn't test it. Am I just having a bad period, or what?
