My periods have always been regular and symptom free until last month. My breasts were tender heavy and grew at least a cup size. I also had terrible nausea and bloating especially when I needed to urinate! Lots of negative pregnancy tests later my period arrived 3 days early which is unheard of on 26/08 and I am now back to feeling nausea to the point I have to stop whatever I am doing until it passes, migraine and breasts are off again. I have never had any pms and this seems such a dramatic changes very quickly. Any ideas?
