So, for the past 4-5 days I've had lower back cramps & cramps in the front but mainly on the left side. The back cramps have bothered me mainly when I'm laying down or sitting. Tonight hubby and I tried to have sex, I got on top & the pain was horrible. Bad cramps all across my lower stomach,& deeper cramps on the left side. I'm concerned. Should I go to ER or wait til the morning and go to urgent care? We are ttc #1. Af due the 13th. Also I've had headaches the past week. ADVICE!!
