I feel your pain on the transvaginal u/s though i don't have a retroverted uterus. (I went through fertility treatments from November 09 to March 10 to get pregnant with this little one and because VERY familiar with the WONDERS of the transvaginal u/s!!! ANYWAYS...I would be a little disturbed that they didn't measure that follicle because if it was getting closer to being 14mm or bigger you have a chance that you could ovulate that follicle and get pregnant. (it doesn't sound like it would be all that horrible if you did catch the eggie...but incase you just aren't ready yet lol) It sounds like your fertility could be returning. Did you get a chance to see the follicle that they saw or was it just on a screen that the tech could see? (At my OB and RE office there was a screen on the wall that I could look at and see everything they were doing) G/L and if you wouldn't mind another little one i'd say go ahead with the BDing lol because ovulation could come soon...though you really can't tell without constant monitoring of that follice. Sometimes they get to a certain size and then they can shrink back up....
