I'm 10.4 as well! Your the first ive seen thats made it as far as me! My DD is Oct 15th and I'm going thru the same thing! My headaches last 2-3 days tho and nothing works and the lower back pains are the worst! But so far those are the only symptoms I've had besides my nose being stopped up lol
I was bothered with headaches before I got pregnant but not everyday and now it seems I can't get rid of them.
Unfortunately the back pain is all part of the fun n games.. my lower back absolutely kills me everyday. Try cold compress then couple days later hot compress, back n forth. Headaches seems to never go away for me even before and after pregnancy. Could be sign of high blood pressure. My ob doctor give me meds for my head that help a little .
