The Alligator Cramps

I’ve been suffering from leg cramps aka simpul biawak for two nights in a row..n It occurs twice every night…It hurts badly…I’ve tried applying Counterpain before bed..but its not much of a help…Can anyone give me tips…I can’t imagine waking up every day to this pain till I deliver..i know it’s common for expectant mothers to experience ths..but can’t anythg be done to prevent it..my hubby will eventually crack if waken by my scream of pain every night….
