I've been thinking for a while that the RE isn't helping you. Correct me if I'm wrong but you had no problem getting pg before you saw her but you have not gotten pg since you have seen her.
Personally, if it was me I think I would stop with the RE and everything that goes with that and enjoy some time with my husband. Remember Kerrie (KinOZ)? She went through several rounds of IVF for a year and even though she did get pg one time with twins from IVF, she miscarried them. She ended up deciding she had had enough and even started looking into adoption. Now she has a 5 month old little boy without any medical help. Maybe a little break, as hard as that is, would be good for both of you. Don't you have a trip coming up with your husband's family? You were worried about flying maybe that would be enough of a break for the two of you? Just thinking out loud. Just don't give up all together. ((((hugs)))
