Differences

Can someone please tell me what Braxton Hicks and contractions both feel like. The internet literally is NO help like ok I get one is false. But how would you know the difference. I think I might be having Braxton Hicks right now been going on for about 4 hrs. Super uncomfortable but doesn’t feel like cramping more like a squeezing uncomfortable feel and when baby moves it hurts a little more. Second time mom but I did not have either one with first baby. Baby was turned face towards belly so all contractions were in my back and butt.
