Hey I'm 35+2 and been having the same. With our 1st I didn't know I was having Braxton hicks till I had a triage visit and they told me what was happening (I thought it was just baby moving in a weird way/wasn't the reason I was in triage) but this time around it's so uncomfortable and it's the same time every night. I had a midwife app today and she said as my body knows what to do, it's just getting things ready to go quicker but can be more uncomfortable as everything is abit more ready and waiting instead of having to prep everything from scratch if that makes sense. She said if I'm concerned about anything then call triage even if it's just to ask advice.
My doctor told me with your 2nd pregnancy you should feel uncomfortable and like hard Betty it’s more common
