Braxton Hicks already???

MistyBenn

So I haven’t gotten this far in a pregnancy in 10 years so I forgot what most of this was like. Could I be having Braxton Hicks already at 21 weeks? It’s the bottom part of my stomach tightening up and almost stings but only when I’m super active. Sitting in fine. Baby girl is moving around so I know she’s okay just didn’t know what I am feeling.
