Im about 9 weeks pregnant and my lower back has started to hurt in the last 3 weeks but ONLY after standing and working long shifts at work. I noticed today while taking my kids trick or treating that my tailbone was hurting everytime i sat down in the car. It got progressively worse over a couple hours and now the pain when I sit is unbearable…It had me in tears! I`m lying on my side which is the only comfotable position right now (or standing) I`m wondering if anyoone has ever experienced this before so early in pregnancy and any clue as to what it miht be? Should I go to the er or wait and see my family doctor..? thank you
