Yes please don’t deliver now. Baby’s not strong enough yet. Get a maternity pillow or at least a bolster for when you’re lying down. That helps to ease the pain. As for walking, well, I needed to take paracetamol on days when the pain was severe (I had pubic symphysis dysfunction). And as I was still working, I just had to walk slowly and carefully. You’re only a few weeks away from being full term. Please hang in there! Take painkillers if you need.
Maybe try to reduce strenuous activity and rest more. Seek your doctor’s advice on what to do.
