Update!

I think I’m starting to have contractions, my stomach tightens and strong cramps, I can feel a lot a lot a lot of pain in my lower to mid back and pain in my legs. I’m dry, no discharge. Contractions are 15 mins apart lasting for a minute. Is this a sign of labor or will I be wasting my time calling my doctor? This has been going on for 2 hours now and the pain seems to be getting worse. I have a appointment tomorrow for nst and ultrasound to check on the baby. Should I wait until then? P.s I’ve been breaking out a lot the last 2 days.
