Braxton hicks or comtractions?

I’m 35 weeks and a few days and I’ve been having super bad what I believe are either Braxton Hicks or contractions. They’ve been off and on since 3 am this morning and are painful enough to wake me when I doze off. I’m not having and water breaking or blood not sure what is going on. Sometimes they are so painful that I don’t even try to time them because when that pain sets in timing is the last thing on my mind I just need relief.
