The night before last while I was sleeping I stretched and got a cramp in my left leg.. I still have pain in my left calf. Has this happen to any of you. I'm scare it might be a blood clot since is easier for pregnant woman to get it. If u did, did it last a few days for any of you .. I read online that sometimes when is a sever cramp it last a few days please help I debating weather or not to go to the emergency because on hand hand I'm scare thinking is a blood clot but I have no su symptoms of being that. On the other hand I think is still cramping
