Early labor?

Morgan • 🌈 baby Kingsley Alexander 7-31-18💕

37 weeks as of right now. I’ve been having period like cramps in my stomach for 2 days now, some one sided back pain on and off that actually woke me up from my sleep. Pressure in my vagina and butt region. A pulling feeling in my thighs, nauseous, and a sharp pain that kinda feels like inside my vagina that’s stopped me in my tracks. I’m a first time mom so I’m worried.
