Hiya, So I went back into epu today for another scan as when I went in Friday they said they saw gestational sac and after extensive looking they found hb but they never gave me any more info other than saying baby was only around 5weeks max.
They had me back in today - 5 days later and they saw everything clearly. It was a pretty quick scan both ab and tv and they said baby was measuring approx 5.1mm crl , they told me it was 1.9 on Friday so had definitely grown lots.
She said baby is now measuring approx 6.2/3 weeks instead of the approx 7 I have worked myself out to be and hb etc was seen both ab and tv.
Does this sound hopeful at all or
should I be worried?
Could 5.1mm be further along at all than 6.2/3?

You can know your ovulation, but you can’t always predict that implantation and growth will have happened at any specific time. They all grow at their own rates, and some start out slow and then catch up and storm ahead. At my early scans, I ended up being a gestation that meant I fell pregnant a full week before I even had sex. The dates don’t mean anything at all. But you have a lovely little baby growing so far so try your best not to worry.

Yes I was the most possible spot on IVF and at exactly 7 weeks baby was 6+4. They weren’t too worried and booked me in for a second scan 10 days later.
At second scan I still measured 3 days too small (but obviously that means the baby had grown in those 10 days)

Also I know people swear by tracking but your body can do weird things like have all the features of ovulation but release later, or release a second egg later, especially as we’re only talking. A few days xxx

Thanks I am more concerned now as I have received my hcg results and although been doubling up to now in the usual times, it was 19233 last Tues and this Tues it was 33901 so not even doubled in a week 😳 That cant be right
