Crampy feeling at 22 weeks

Hey ladies! FTM here. Wanted to check in and make sure I'm not ignoring an important symptom. For a couple of days now I have been having light/mild cramps without bleeding in my lower abdominal/pelvic area. It doesn't disturb my day or come with any other symptom but does concern me since I haven't felt this since early, early on in my pregnancy (4-6weeks). I'm drinking plenty of water and using bathroom normally. I have also been feeling baby boy moving normally every day. I do have an appointment this upcoming Tuesday with my doctor. When I Google it, it says it can be BH (Braxton Hicks) or round ligament pain. I don’t know what a Braxton Hicks feels like so Im not sure. I do feel like my belly is tight and stretching so maybe it’s that? Any insights ya’ll? Kinda nervous about it now. 😓thanks!!
