Off clomid now...Does our timing sound right?

Sounds like you timed it right! I would have BD'd the day of ovulation as well just to increase the odds but even if you BD 3 days before O you've got a good chance of catching it. With a "normal" 28 day cycle you should ovulate on CD14 so ovulating on CD16 is great! Every woman is different and every cycle is different. I've never O'd on the same CD while I was on Clomid. I'm surprised he did not do the semen ysis before starting you on fertility drugs, usually that's the first thing to happen. The Hysterosalpingogram (HSG) is a relatively expensive procedure (though not nearly as expensive as IVF - mine was $1,000 without any insurance coverage) but it is done to check to see if your tubes are blocked. If there is some light debri in your tubes the procedure can sometimes help clear your it but if there is a true blockage then it could need surgery to clear it. Anyway, I think your timing is good and I hope you get your BFP this time : )
