painful menstrual cramps?

So I'm almost 37 weeks pregnant and I got to say one thing I've really been enjoying about pregnancy is not having my period. I'm dreading having my period again. I have really really bad menstreal cramps that  some times cause my face to go paler, I sweat, have chills, I've thrown up on one occasion because of it, I get diarrhea, and my cramps feeling like I'm being stabbed they are extremely intense and actually make me feeling very ill. Keep in my mind I also have a pretty high pain tolerance. I feel like this is extreme but I've never really talked to a doctor about it. It's great that I haven't had to deal with it for nine months but now it's getting closer and I was just wondering if anyone else has a similar experience with their period or if their dreading their period coming back after pregnancy. If you have similar symptoms is it a condition that I should consult my doctor about?
