Nightly calf cramps

So this is my 3rd pregnancy and I thought I had figured out how to stop a calf cramp when half asleep and stretching in bed.

Well this morning at 4:45 i got a cramp in my left calf so I flexed my toes back like I’ve always done to stop it. Well flexing my toes back caused a cramp on the SIDE of my calf! I could not flex my foot forwards or backwards without causing a cramp somewhere on my calf! I was still half asleep and fully woke up almost in tears and could not figure out how to make it stop. Massage and putting weight on my leg finally ended the pain.

I have two weeks left before induction... I hope this doesn’t keep occurring!

Anyone have any other tips for calf cramps?
