muscle cramps!! pg?

I've been drinking enough, well as much as I usually do (which is a lot TBH). For two days I've had serious cramping in my muscles. My legs, abdomen, hands, etc. My thumbs are cramping a lot and out of nowhere. My legs are achy and cramping in areas I never knew were there lol. I bent over today a few times and my abdomen cramped so bad! Like the muscle up top. I can still feel the discomfort from it. I've never had low potassium so idk what to do. AF is so irregular but I might be 4-13 dpo. More towards 13 in my opinion. I didn't temp or anything this month....
