I am not sure about your legs cramping, most people have strong period like cramps and I think that I have heard of a tender stomach but you should really watch it. I had a lot of lower back pain and cramping then the bleeding got heavier and was real heavy for about 2 days, just make sure to wear pads and not tampons (i don't know if your doctor told you)
i was about 6 weeks so I bled for about 7 days, but everyone is different.
Then I passed the tissue that is why you need to wear a pad and because of infections, and I saw on your other post about sex, and it should be avoided until after you have stopped bleeding, it is not like period sex! That is what my dr said anyways.
Sorry for your loss and I hope all goes as well as it can!

Thanks!

Well how will you know if you passed the tissue. Thats all of the clotting right? My doc didn't say anything about the tissue I just have to go in next week to start doing blood work to make sure my level goes back down. But she did tell me to make sure I either don't have sex, or use a condom.
