Hi ladies just looking for a bit of advice. Went for early pregnancy scan 2 weeks ago for them to see a sac of 4mm went back yesterday for them to still see a sac now at 6mm the nurse told me the pregnancy does not look viable and to go back next week. I think I'm about 5 weeks so I am getting myself all worried and an emotional wreck should I of seen a yolk sac by now or has this happened to anyone else and all been fine. Thanks ladies xx
