Braxton hicks or contractions?

Taylor

Anyone else having a hard time deciphering between Braxton hicks and contractions?? This is my second baby and these feel so different then they did with my first way more pressure down low in my belly and it moves up to the top of my belly. Making me super nauseous. But I have tried hydration and relaxing and it doesn’t seem to help. And it’s making the baby move around like crazy. Anyone else experiencing this? 33 weeks this week!
