Anyone else randomly gotten rounds of the shakes at the end of their last trimester? Half the day today I just randomly start trembling/shivering for up to like 10 min at a time and then it stops for a while. Then repeat. I know it isn't my blood sugar and I'm not cold. I'm a little freaked out by it, because I know what it isn't. Oh, if it makes a difference I've been told I was in early labor for just over a week? Anyone got any experience/ideas?
