I know exactly how you feel and I'm so sorry. I had 3 dd's conceived first month of ttc, dd#3 we swayed and failed, then high tech our first cycle produced 5 girls vs 2 boys (which also gave me not much hope of ever conceiving a boy naturally). 2 fantastic embryos, first one transferred = BFN and the 2nd didn't even survive the thaw. DH was adament that 1 cycle was IT!!! After talking him into another cycle - the next one was cancelled just before egg pick up due to high risk OHSS, I was losing hope this was ever going to work. Next cycle, only 4 went to PGD and I was devestated knowing the gender balance from cycle 1 what chance did I have. I eneded up with 1 boy and 3 girls - I was happy to have transfer but also sick knowing that this was likely my last shot at EVER having a boy..........and he's now my son!!!
Sometimes your first round of IVF is like a bit of a trial, maybe if you give it one more shot, you may get better results and possibly get your BFP. It's such a hard road to take, I know, you invest soooo much money and emotion into it that it's hard to know when to stop. Goodluck, I hope your daughter finds you!!
