Symptoms are presisting. Most of the back pressure is gone for now but im having pre contraction pains in my lower stomach and im having to go to the bathroom every 5 mins bc of constant pressure on my bladder. Gotta go to my last birthing class tonight, but to afraid to drive myself. I dont think i would be capable of it anyway with how i feel. So im having my sister take me there. My husbands gonna meet us up there and then after class hes gonna bring us back home. Bout to take a warm shower. Hoping it doesnt make the symptoms worse.
