I'm 34 weeks FTM. Just yesterday as I was walking around the mall my back began feeling sore. I thought baby is heavier it's probably normal. Then like two hours later my butt began feeling weird. Like when you sit on an uncomfortable chair for too long. It's morning now my ass still feels the same. It's only the buttcheek area like if it's sore. I told someone who's had three kids and they said well that's weird. What? Anyone else had this weird feeling too?
