Sensitive tummy?

Mommy Of 2

Any one ever experience sensitivity below the belly-button? I’m 18 weeks pregnant, and it’s been pretty sensitive for a few weeks or so now. And sometimes it hurts REALLY bad, I dont feel like I have too pee, but then when I go pee, it hurts twice as bad as I sit down onto the toilet- but after I pee it’s fine? Like is that normal? FTM
