I conceived for the first time after 9 months of not trying but not preventing when I was 34(DS). Hit the jackpot as the month I conceived we only BD'd once!
Took five months when I was 37 but ended in the stillbirth of identical twin girls (no age related problems). 11months age 38 (blighted ovuum), 1 month at 39(DD)and first time lucky at age 40 (DD). This was shortly before my 42nd birthday. 2 months when I was 43 but ended in M/C due to cord accident (no age related problems).
Have been trying for 12 months now and am now on Clomid (2nd cycle). Seems that I have a progesterone shortage (short luteal phase) so fingers crossed it doesn't take much longer.

Good luck to you.
