Advice please ladies! For about the last week I've been really nauseated, getting very hot and dizzy and (TMI) diarrhoea. Then this morning I had two really bad nose bleeds to the extent that blood clots were coming out of my nose, I've never had nose bleeds before. Getting quite worried about how sick I'm feeling though :/ anyone had anything similar during pregnancy?
