BH same time every night

Kiff
I'm 25 weeks and have been getting Braxton hicks ever since around 20 weeks. For the past week I've been getting them around the same time every night. I get them throughout the day occasionally, and they're usually pretty mild. But around 9-10pm I get them pretty strong (no more than 3). I drink a ton of water to make sure it's not dehydration. Do you think this has anything to do with the time I'll go into labor? Or could this possibly be a sign of preterm labor? I'll be asking my doctor on Monday.
