I posted on the miscarriage board but haven't had a response so thought I'd ask here. I'm spotting & I suspect I'm starting my 4th miscarriage. I am wondering if the hcg injection will prolong an inevitable miscarriage. I would like to hear from others who have been advised to have these weekly injections by the recurrent miscarriage clinic. I had my first injection yesterday after a faint positive test on a frer. I am cramping & spotting.
