Stomach & back pain( Need Advice PLEASE)

Ang • Mother to Xavier & Naomi👨‍👩‍👧‍👦❤ Baby #3 due February 2020 💚
I'm 36 weeks pregnant & 2 days. I woke up last night in the middle of the night to horrible stomach pains, drank water & layed on my left side. Pain continued for 3 hours than I finally fell asleep during it. Woke up this morning (around 8 am) with cramping, & minor back pains. Now the pains had gotten intense but to me it feels like gas pains that comes & goes. I haven't been timing them because I don't want to get excited and go to the hospital and false labor. I'm a FTM, what should I do??
