I think if you use the HCG and clomid or nolva even on a cycle you will bump your count. The diff is that it will go back down due to the presence of exogenous test. Hell My wife came off BCP and I came off test and deca. I waited a month and started HCG and nolva. She was pregnant the following month. (I have a sneaking suspicion she stopped taking her BCP before this though)

All it takes is one strong swimmer. There are just FAR fewer while on.

Best chance to get her preggo. come off and do PCT.
