Anyone have this happen to them?!?

I am currently 32 weeks So this morning at like 5 in the morning I woke up with super bad cramps like horrible. It felt like o was on my period times like 5 lol and so I got up and went pee and it hurt so bad that's sat on the stairs right by the bathroom, I was about to wake my mom up and see if I could go get checked out because it was seriously horrible! Well I went into my room and later down for a little bit to see if it went away and then I ended up falling asleep and woke up like 2 hours later and I felt normal again! And then I realized that I can never lay straight on my side like I have to be propped up with 5 pillows or else I feel like I can't breath but I woke up flat and now I can breath perfectly fine laying down! And I haven't been able to sleep without being propped up in probably 3 months now
