Hi, I'm terribly worried and dr hasn't really explained. LMP was 14/4 which would make me 7 weeks today. Positive test on 19th May confirmed by bloods (HCG 102) an CB indicator all point to me being just over 4 weeks when I found out. We have been trying over 2 years and under fertility consultant. Had ovarian drilling op where they also found endo and heart shaped uterus on 2nd March. Couldn't believe it when I got positive test but at 7 week scan last night they could only see gestational sac at 4.2m, no yoke or anything. They want me to come back on 14th for another scan and took blood today. I'm terrified sonethings wrong. They said my dates could be out but how would I have got hpt bf on 19th if they are right and I was only 2 weeks? Though at 2 weeks you only just had implantation?
