Labor or Braxton Hicks?

So I woke up this morning around 7am and went to pee... I felt like mild period cramps but I thought it was because I hold the pee for too long and just kept it moving. I kept feeling it but I was like it will go away but it hasn't 😩😩😩😩😩😩😩😵‍💫... it feels like period cramps and like when you eat something and doesn't sit good in your stomach or you have gas in your stomach. Every time I feel them my belly gets hard.

I am 26w2d with Di/Di twins and I am starting to worry 😣
