I'm 32+6 weeks and starting to worry today. I've had a headache for two days so I'm not moving around much. Therefore I should be feeling my baby kick more. I felt him plenty yesterday, but as far as I can remember I haven't felt him at all today except maybe once at around 4am(ish?). I had an episode last night where I couldn't hardly find a painless position to lay down in, almost all positions caused this sharp, intense abdominal and low back pain. I also felt some cramping yesterday afternoon, almost felt like menstrual cramps. I've just now realized I haven't felt him all day because I've been in/out of naps (trying to get rid of this headache). When should I worry?
