Hay good luck TTC, I had a friend whom tried for 6 yrs, and I fell pg with the twins, not on purpose, I felt sooo guilty that I was and with 2! and she couldnt seem to get there, but when I was 6 mths pg, she fell pg too!!!! Then they tried IVF for nearly 2 yrs, well I fell pg with Rianna ( again not on purpose) 3 mths later she had a successful IVF implantaion, so we used to joke that I had to be pg for her to fall pg, so it might be the same for you and your friend, you will be pg, when she is!!!!!
