Braxton hicks?

Hi all, I’m currently 18 weeks 1 day and last night I had this weird ache all around the front of my belly just not low down, it felt like a growing pain or a strong period ache but it wasn’t painful it was just uncomfortable. I didn’t feel anything else and it only lasted less than a minute or just about a minute.. it hasn’t happened since and I feel fine now. Anybody know if this is Braxton hicks or something else
