32 + 3 BH or contractions?

I am having tightening of my abdomen. It has been happening for about 8 hours and getting more frequent. They don’t hurt just feel like squeezing and uncomfortable, particularly below my ribs but above my belly button. It’s just worrying me because they are becoming more frequent. I have a normal appointment for tomorrow so I will mention it.

Has anyone had this before? Does this sound like Braxton Hicks?

Thank you!
