Stomach cramps and lower back pain

Tiana • Mama to a beautiful boy 💙

So I've been laying down today due to having a cold, being extremely tired, and pelvic pain. I just got up and as soon as I set myself up there was like a shock that just spread to my entire stomach and now it's like I'm having stomach cramps and lower back pain. Bout to take a hot shower to see if that will relieve some of this pain, but if not should I just lay down and see what happens or just go ahead to labor and delivery?

S/N: I haven't had any labor signs. I'm 36weeks and 3 days.
