Yesterday I went for an early scan as I have previously had a miscarriage and eptopic. At the scan they couldn't see a yolk sac or fetus but I my gestational sac is only 5mm so they said this could be normai if I am only 4weeks preg. Last week I did a digital preg test tho and it said I was 3+ which means I was more than 5 weeks preg. I'm worried that I may have blighted ovum... I have dull period like pains at the moment. Can anyone help?
