Am 17 weeks with dc2. I have a niggling muscular type pain in my groin. Worse today after pushing ds1 up pretty steep hill in pram. Quite sore, but better if I lie on side so weight of bump is off my pelvis. Could this be early SPD or something else? Getting worried that if I'm sore now, what will I be like by the end. DS1 is a handful and a half so taking it easy is quite hard unless I'm at my desk at work!!
