Went to get some more food before we get more snow at Kroger and was walking around and in my left side I got this pain that was hurting when I walked, had SO go find me a cold tea and it helped but still felt the pain.. It's gone now but my pelvic area is hurting a bit.. Wondering if this is a Braxton hicks or contraction or just round ligaments. Wish I could explain it better lol
