Kinda worried..

I'm preggo w/ twins 16+3.. Since like 8 weeks I've had bad groin & ligament pain.. Idk if my tilted uterus accounts for this. Sciatic pain.. Leg pain. Whatever it could be lol I've had it except for much nausea. Well up until 2 days all it was constant then like it all just stopped.. Should I be worried???? I feel completely normal & that's kinda scary.
