I had a miscarriage 2 weeks ago and I've been having extreme back pain. I'm also very weak all the time, and when I stand up, it gets worse and I have to throw up. This is my 4th misscarriage in the last 2 years and is going to be my last try. I have a 4 year old. I didn't go to the doctor b/c I was pretty sure it had all passed but with the symptoms I'm having this time, I was wondering if anyone else went through this after a miscarriage?
