I just found out I am pregnant at the weekend. I have irregular periods and a history of miscarriages. Anyway I thought I might be 6 weeks but had a scan and measured by 5w 2day. We say a gestational sac measuring 7.15mm and saw a yolk sac but no fetal pole or heart beat. Anyway I had some spotting the past few days every light and only when wiping. Now I am freaking out. Could I be miscarrying again.. I have had intermittent cramping but no bleeding and the size of the sac is freaking me out.. is it too big?
