I think I might have had a miscarraige on July 30. Can anyone tell me what the symptoms are like?

I have been in and out of the ER 5 times in the past 3 weeks. I went to my general Dr. on July 39 complaining of heavy l bleeding and severe pain and cramping. He did not run any tests on me and prescribed me Darvocet. I have been have been taking tons of tests and they're checking my Gall Bladder but cannot find anything wrong. I'm still in severe pain and was wondering if I should be seen again for this reason.
