Braxton hicks contractions???

Ok so I know people ask this a lot and I'm really not sure this is what I'm experiencing, so if you can relate please let me know.

So I get this tightening feeling in my stomach and it's painful. Makes me want to get sick every time it happens. Well the pain starts at the front of my stomach and immediately my whole stomach starts hurting. Feels like tightening/cramping. Goes to my lower back and then back to my stomach. Laying down doesn't help, drinking water doesn't help, rubbing my stomach doesn't help. A bath doesn't help!! Nothing helps. It lasts at the least 15 mins but it has lasted almost an hour once. I'm getting this pain at least twice a day or every other day. Too often if you ask me. I'm having extreme pelvic pain. Like my crotch hurts. I'm not sure if I should be concerned or if it's normal.
