Worst day ever...tempted to cancel the cycle and get my money back. Had a follicle scan today and they measured nothing but claim there are way too many eggs. They are looking at quantity and not quality. Don't even know the sizes or my lining. Drew my blood but never got the E2 level. He's saying there are too many and they may retrieve them but do a transfer at a later date. I'm livid...been crying all day. I want a chance with some fresh ones. Oh and I got the bombed dropped that it's an additional $1200 to take them to blast which they almost guarantee they will do. And this is after the 9k I paid them up front for what I thought was everything. And my labs aren't covered there since they do them in-office and they are $400 each with me having 2 already with 2 more. And....the major source of stress is once they freeze the embryos...wait for it...it's $5150 to transfer them for a FET!!!!!!!!!!!!! I've only ever paid under a thousand for that. I'm sick to my stomach and in tears. And to top it off my car has been struggling to start all day. Think of me girls...
Dearest, firstly,

! I pay out of my own pocket too and know how frustrating it all is. I had a similar situation as you but it happened just before ET.
I have PCO, scanned and showed more than 55 follicles. 49 retrieved, etc etc. During Egg pickup, I was told that we will try for day 3 transfer (Saturday). Come Friday, I saw 12 missed calls on my phone as I had silenced it. Called back and the hospital wanted me in for a Day 2 transfer at 2pm! OMG! I had 3 hours to get ready to go and my hubby won't be able to be there with me because he has work.
So I went in, another twist. They wanted me scanned to see if I had OHSS from having so many follicles (same as you). If I had OHSS, they won't transfer. They will freeze any embies I have that survive day3 and do a FET. I had never experienced so many sudden changes in any of my ICSI cycles. (damn the PCO!)
Finally, at 4.30pm, I got my transfer done, a 2-day instead of 3-day.
I can totally understand how you feel. Building up the courage and emotions, for D-Day and then to be told otherwise. Howver, my doctor and nurses explained me through every single step. I think what lacked in your case are the FS not explaining to you in detail. It is horrible to go through so man things and not being explained to. I suggest you call them and ask for more details because you deserve it babe!
