Is anyone getting Braxton Hicks contractions?

Is anyone getting Braxton Hicks contractions? I am almost 21 weeks and today I started feeling something weird in the lowest part of my uterus, like just above my vagina in the inside, like if the baby was kicking that way or my uterus being dropped for a second. I know I am not doing a good job describing this feeling, but I hope some of you know what I mean or someone has felt something similar. It doesn’t hurt and there is no pattern on how often do I get them so I am assuming this are the famous braxton hicks thingies? Thanks for reading ladies
