32/33 weeks pregnant, my stomach has been so sore and just in so much pain from my stomach and waist down... down there is swollen, and hurts to wipe after the restroom from just soreness (no me and my s/o have not had any sex recently) and all my thighs and legs are sore. should I be worried? it hurts to sit up, lay down and stand up... my aunt said I might be going into premature labor its been like this for 2 days now and baby is active.
