Yes I'm 4wks 5days and I'm having terrible back pains but only at night. I didn't even know I could get back pains this early on. With my first pregnancy I didn't get back pains until around 37 weeks which seemed obvious since my belly was so large.
extremely normal. I just had my first baby on 10/20/14, and I worried about EVERYTHING! lol only take TYLENOL, NO Ibuprofen, and if it gets worse then definitely see your doctor! congrats & good luck!! (((:
