Butt cramps?

[Softmama]

I have been experiencing really severe cramps on one side of my butt!!! Also having severe but fleeting cramps in my groin on both sides (low down, almost in the leg more than the groin). Has anyone heard of this? I am 37 weeks pregnant with #2 and never experienced anything like this the first time around. ANY suggestions would be appreciated as I am hobbling around my house.
Thanks

Yep, I had them so bad with Riley that once I crumpled to the floor. They really hurt don't they :(

Maybe try to get some potassium / magnesium in your diet?

No real advice, just sympathy!
