Pelvic Soreness

Phebia • TTC after our first pregnancy/miscarriage 12/02/16. Hoping for a 🌈.

I'm 33.5 weeks with twins. The boy is super low and pretty much laying in my pelvis in breech position. I have started to have pelvic/groin soreness that is worse when I've sit a while and then get up and walk. It's not really painful or feels like pressure it literally feels sore like almost a pulled muscle. Anyone else? I'm afraid I'm going to go into labor and not know it.
