Hi Kooky, I'm 11 weeks and my lower back has been hurting for more than a week. It gets extremely painful at times and feels as if it were giving way when I bend a little. The ligaments and muscles are expanding and stretching to cater for your LO. The front of your tummy too. I've asked around the forum, the pharmacist and also my doc...nothing much can be done to ease the pain other than taking paracetamol, a heat/cold pack or swimming/yoga to strengthen the muscles. I'm refusing to take any paracetamol if possible, hence am using the heat pack. Am waiting for our new place to be ready and will have a small tiny pool to swim in, hopefully that'll take some pain away.
