My FS assumes we will keep going each cycle until it happens, but I definately won't feel bad for taking a break, we are the ones paying, we are the ones who go through the stress each month, we are entitled to say "I need a break" and make that decision ourselves (but hopefully it will be because I wont need it like you said).
Hehehehe, I've still got a blog if you can navigate it lol. Hopefully I won't need a TTC blog anymore, and I can start a pregnancy blog soon! Good luck to you too.
