Terrible cramping

Randi
So I went in a couple weeks ago for cramping because it just wouldn't go away but I had a terrible experience and found out nothing.
Last night my husband and I had Sex, for the first time in a long time, months probably because I just don't want to do it. And that may have nothing to do with this, idk. Anyway I'm having the worst freaking cramping in my lower abdomen and low back pain. I have contractions every day and it doesn't feel like that. But this really hurts and the dr I saw a couple weeks ago gave me no advice for cramping. Anyone have any advice to help? I've had a few really strong pains in my butt/vagina which happened a lot when I was going to get my period. I cannot get comfortable and I'm starting to get nauseous. Any advice is appreciated!
