Anyone have success using Pre-seed?

I'm 26 (soon to be 27) I was diagnosed with endometriosis a few years ago. My husband and I have been married for almost 10 yrs, and tried to start a family right away with no luck. By some miracle 7 1/2 yrs later I was pregnant. We now have a beautiful 18 month old boy. We were told to TTC by the time he was 6 months old for best chances and we have had no luck. Recently my OBGYN has told me to try using PRESEED, as it has helped many of his other endo patients whose conditions do not qualify them for surgery, or can't afford fertility aid, and that it has actually helped them conceive. Just curious if anyone has had success with it after struggling TTC.
