so basically i do not know anyone and havn't chatted to FS yet about it but want to get any feed back on using a sperm donor, doing a natural cycle, as i have a very regular cycle and very fertile.
Hi JBM,

I am a donor.

Since you are quite fertile then suggest to your FS that you want to do IUI with a natural cycle (as you have proposed). If the FS does not agree with you then maybe talk to another FS.

Good luck.
