Meredith, glad 13 of them are still going...about the transfer, the clinic always incline to transfer the strongest one as they are trying to get you pregnant asap of course. But in this instance, I would request to freeze the top performer given your current lining situation.
Another thing I have always wonder is - seems stim cycle never worked for me, even last time, two perfect 5 day blasties...the only time I got pregnant is from a FET cycle. I think because our body has been knocked around with all the poking and drug and EPU etc and might not be in top condition while FET is the closest toward natural conception. WTH also posted a research earlier in the thread about the IVF clinics in Japan has stopped all fresh transfer because FET seems to have higher success rate. Correct me if I am wrong WTH, but it has something to do with E2 level as well. If I can have last cycle all over again, I certainly wouldn't transfer two, I feel I've wasted a perfect embyro, I would transfer a less stronger one and freeze the best for FET. For one, it has better chance to survive the freeze and thaw, for two, there is better chance in a FET cycle. But that's just my personal opinion hun...do what you feel comfortable...

AFM, 1st b/t and scan this morning, everything seems ok, I have 8 follicles on the left and 8 on right, lining is 6mm. Nothing much to report really.

Hope everyone is having a cool weekend. Here is getting hot already. I am not too fond of 'hot weather', normally I am 'hot and bothered' in this heat.
