Dropping hcg after transfer

[E1234]

Hi
my hcg levels are dropping from 70 (10 days past transfer) to 58 (12 days past transfer) 😔 Just wondering when I should expect to bleed/does this tend to happen quite soon after levels coming down? Haven’t had any bleeding or cramping yet. Thanks

Just incase anyone in similar situation and wondered the outcome I eventually bleed 7 days after first blood test x
