Okay, so i've been having regular period pain cramps since roughly 5pm tonight, they started off every 20 minutes and have been every 10-12 since about 7pm. Im 35+2. These aren't my braxton hicks, as these feel completely different. They've become weird now, my whole abdom hurts with them and i feel sick, ive had to go for a wee about 6 times in the last hour, and i constantly need feel as if i need a wee. I had a bit of a show about 5-6 days ago, but nothing since, my back is agonizing and the pain isn't getting better if i move or change position! Help or advice? Please?
