Girls, it's scary, I've been having cramps in my lower abdomen for two days now, probably training contractions. My last ultrasound was December 16th, there was an opening of 2 fingers, they said I could give birth much earlier, just keep an eye on myself and here these two days I eat like a glutton, my belly is full, but I can't eat anymore, and today the little one has been very active all day, not even for an hour does she calm down. A couple of days ago there were some discharge, not much, a bit of a cloudy color, mucus (I think from the morning-after pill). So, is everything okay with me right now? To the doctor
