I'm 12+4 and since my scan on Tuesday I've had backache it's coming and going but here for a few hours at a time. It feels like period pains in my back at times I can't really describe it sometimes it's in the middle of my back sometimes the lower back all I know is it's uncomfortable. I went to the doctors Wednesday as was quite worried about it and had abit of blood when I came home from dating scan however epu weren't concerned. But still anyone had this it's driving me insane??
