Okay mama’s this is my first baby so I’m new at this.

Last night I started having what I thought were Braxton-Hicks so I took a warm bath and drink a lot of water and they stopped. This morning I woke up to a pain that was a mild period cramp and I’ve been having them again strong on and off all day. Well about 2 hours ago I started getting this period cramp again that also feels like a really bad gas pain. My stomach is getting really hard and really tight and I’m also getting back pain. It feels like my baby is curled up in a ball every few minutes. I can see my stomach go in a huge bump every time. They are super painful. Do you think this is still Braxton-Hicks or is this contractions?? I have a doctor’s appointment first thing in the morning.
