I got it really bad during my 1st pregnancy, my Dr said it was lack of calcium so to increase your dairy intake, I also took another calcium tablet in addition to my normal multi vits. She had also said to stretch out the calf muscle every night before bed. That worked for me, if I didn't stretch I got the cramps and I could barely walk for days too.
This pregnancy I have been drinking heaps of milk and taking Elevit and I have only had 1 severe cramp about a month or 2 ago.
