Cramping after bleeding has stopped


Hey ladies-

I was about 5 1/2 weeks when I started bleeding (exactly 2 weeks ago). I bled for about 11 days with lots of clots and now have only had super light pink/Brown spotting the last two days. Last night I started having bad cramps and abdominal distention. This morning I woke up and it was worse and I was very dizzy and blacked out for a few seconds.

Is this a normal process of miscarriage?? I never did have bad cramps when I was bleeding.
