I got my BFP at 14dpo, with the HCG levels being only 27. Exactly 14 days later my levels were 15,701.

I had my dating scan when I was supposed to be 7weeks 2 days, but bb was only measuring at 6 weeks 3 days.
I had a small amount of brown bleeding at 8 weeks 4 days, and had an emergency scan followed followed by a proper scan at 9wks which showed that bub was measuring exactly on the dates were given at the dating scan.
It turns out I actually O'd late and implantation occured a bit later than normal too.

I'm keeping my fingers crossed for you that everything will be fine darl! Sending you some HUGE HUGS!!!
