Lower abdomen hard

Marcia

Hey ladies, I'm 35 weeks and my lower abdomen (above pubic bone to halfway to belly button) is constantly hard and tight. It's not Braxton hicks but I think its because she's head down? When I get Braxton hicks, it's my entire tummy and lasts about 20-30 seconds. I didnt feel this lower tummy thing a week ago and she's been head down for almost a month. Anyone else experiencing this or know why?
