Retrieval scheduled for Friday!

So excited! Tonight we are to trigger and retrieval is on Friday. I stimmed for 9 days and today (day 10) I do trigger, Lupron, and ganarelix. Today they told me they are canceling my fresh transfer and told me we have to do a frozen transfer. They have been preparing me for that news since they suspect I have PCOS from the number of follicles they see on my ultrasounds. About 20 on each side. Not sure how many I really have but will know for sure on Friday after the retrieval! Who else is having one soon??
