Braxton Hicks or contractions??

I’m 35 weeks and having sharp pain across my abdomen from my belly button down. This is my first pregnancy so I am unsure on how they feel like. It also happens when I pee tmi sorry lol but it tightens and sharp pain across my abdomen. I also have really bad pressure down there but I think that is normal at this stage in pregnancy. I also been having these pains since last night and throughout the middle of the night. They are on and off but not consistent.
