Natural insemination

My husband and I have been trying for over a year now. He has low sperm count and we have been working on getting his numbers up...he quit smoking, is taking supplements and was prescribed Clomid. His numbers are up a little bit but still low. We are getting ready to try a natural insemination since I ovulate pretty regular we chose for me to not take any drugs like Clomid. Anyone have success story with natural insemination? I'm just getting nervous and would love to be pregnant.
