Following a FET of a single blastie, my BT results are in and it is positive. The HCG levels are 900 with good progesterone. I have 15mth old twins and at the same stage, the hcg levels were only 300. I am terrified that I have another set of twins on-board.
I would love to hear from others what their hcg levels were at week 4 and if they went on to have a singleton or multiples.
Thanks in advance
