What is up with these leg cramps???

AJ • SAHM of 2 (👦 4YO, 👧 5YO) Oh yeah, I have a husband too lol.
Woke up for the second time this month with a cramp in my calf that made me cry.  This was way worse than the one before... the muscle was pulsing and would not stop for a good ten minutes.  I woke my poor husband up and everything. 😩  and that leg is still so fatigued, took a while to get out of bed and feel like I wasn't going to fall.  Does anyone have some recommendations for preventing or helping get though these cramps?
