It really depends how far along you were I think. I was 9 weeks and had cramping so bad I thought I was actually having contractions! I had some sort of water-breakage too, (I could feel it and upon describing the feeling to the doc. he agreed) and I could feel the fetus flushing out when the cramps got to their worst point and I spent some time sitting on the toilet for it all to be over. After the fetus passed, the cramps stopped, so all in all it took about 2-3 hours of cramping and 1 min. of "flushing" I think.
I used an electrical heating pad but no pills. I bled for about 1-2 weeks afterwards but not really bad.
Then my regular period came about 4-6 weeks later.
Good luck to you and I'm so sorry for your loss.
