First IVF meeting with the clinic

My husband and I are in our tww of 2nd iui and going to move on to IVF if we get another bfn. We had our first meeting with the ivf clinic on Friday, 3/29, but they were already booked for May retrievals so we would have to wait for June for retrieval. I was so upset that May was full, and mad at myself for not starting the ivf process sooner. We are on a waiting list in case a slot opens up in May, so fingers crossed! It's so hard to be patient in this process, we have been ttc for 2 years plus decided to try iui first, ughhh! Also, we decided to do PGS testing on any embryos we get, so no fresh transfers... which means, if we do get embryos that pass pgs test, transfer would take place in July... seems so far away! Also, my doc strongly recommends only 1 embryo transfer at a time. We also decided not to do ICSI. We do not have Male factor infertility. Any similar stories out there???
