Are these real contractions or Braxton Hicks?

I’m only 19 weeks+2 days. Going into labor before baby is viable is my absolute biggest fear. It’s like a bad period cramp in my lower belly, and then the most recent one I had, the pain started lower belly and moved to only one side of my back. I felt 2 of them about 2 hours ago, and I went to sleep, hoping to wake up and feel better. But they’re still happening. They last about 10 seconds

I’ve only had one since I woke up, I woke up about 30 minutes ago.
