I have a quick question mommas? ok...this morning I walked for 30 mins...came back home...sitting here and I don't know if it's just me but I've been getting like these Braxton hicks I think in my hips and goes to my lower back...and under my stomach where my pelvic bone is at...it's just constant...should I keep an eye on it or do u think it's cuz I walked?
