Thanks ladies, it was a mix of good & bad news. The good news is that my levels of hcg have risen from 17 to 26 but they havn't doubled which they should've really. It does mean that it is unlikely that I have miscarried however I am at high risk as normaly the hcg would be in the hundreds by now. I have to go back on Friday and that will be the teller as if bub is doing ok it should've at least doubled.
Keep everything crossed for me please, hope your all doing ok xxxxxxx
