Hey Roni! Unfortunately I don't think there is an answer for that! I think it's just one of those things that some people are able to put out of their minds. Maybe some get mad and say just it and forget about it. Others may try to occupy themselves with another interest. I'm sure it's never far from thought, but it's just how you decide to approach it.
How long have you been trying? I know some people have tried for months and years, I would imagine after a certain period of time, you get used to it and can maybe not think of it as much. But that's only my thoughts. I have been very very fortunate in ttc and I don't take it for granted for one moment.
Good luck Roni!! I hope it's not much longer for you!
