SORE BELLY

I’m 31 weeks pregnant and I’m starting to feel the “bigness”

I’ve had Braxton Hicks for a while now, like 8 weeks. But last night I had a long, tight hardening in my belly that actually hurt. Felt like a Charlie Horse.. it went away but all night my belly was sore. And still throughout the day today it’s been sore to the touch and kind of ache-y. Like I did a bunch of crunches or something.

Any insight? I haven’t had another “Charlie horse” feeling in my belly since. Just soreness. Normal?
