Advice please? BH contractions!

So with my first I was in the hospital almost weekly with issues, and ended up with severe preeclampsia and preterm labor. (Made it to 37 weeks & emergency c section)

Anyways. So now with my second, I have had 4 different “episodes” of Braxton Hicks that won’t go away for hours. I check all the bases (lots of water, moving positions, use the bathroom, resting, etc) I live an hour from my obgyn so it isn’t easy to “just go in” and find someone to watch my toddler at midnight...

Last night I was contracting painfully every 3-5 minutes for 4 hours. I know you’re supposed to call if you have 6 in an hour, but each time they have stopped eventually. At what point do I really go in and when do I just assume this is normal for me? I’m just at a loss at this point. I don’t want to be paranoid just because my last pregnancy was so awful.
