I had my last menses on 15th December 2013, as per which I am 8 weeks 2 days pregnant today. I previously had inconsistent periods, so my Doctor said it can be delayed conception. I went for my Trans Vaginal scan today, which said GA of approx 6 weeks 1 day, crown rump length 0.51 cm, yolk sac and fetal pole are well visualized, however cardiac activity not visualized within fetal pole. I am really worried and I desperately want this pregnancy to grow. Please help
