Yep - first time. I was very, very lucky although my problem is not getting pregnant but getting a bub to stick.

There seem to be differing views on how often you should DTD around ovulation, but my FS's recommendation was day of shot, day after and if we felt like it, the day after that too. I was also told that ovulation would occur within 12 to 24 hours of the pregnyl, so your Dr's recommendation of the day before sounds fine to me.
