Hi butterfly, sorry I've not updated much recently. All sort's happened, but I've been posting on Purple's thread under my current MN nickname, BlueKarou, and have neglected this thread. 
A quick runthrough of the past fortnight;
I had a scan on Friday 22nd, which showed my follicles were growing, but not as fast as needed to schedule collection, so I went back in for a third scan on the bnk holiday Monday (25th). They initially booked me for another scan the next Wednesday, but by the time I'd got back home I'd received an e-mail with instructions to go ahead with my trigger injection that evening.
Egg collection was Wednesday 27th May. It was the weirdest thing so far. I was all gowned up, and went into the small theatre where they strapped my legs into stirrups and put me under sedation. I woke up 20 or 30 minutes later and it was all done. They got 12 eggs from me. 6 of these went to my recipient, and my 6 got to mingling with my donor sperm.
I got the call the next morning to tell me 3 had fertilised normally, and transfer would be either the Saturday or the following Monday, depending on how things progressed. The Saturday morning's call told me all three were still ok, and to come in on Monday 1st June.
So on Monday 1st I went to the clinic. I learnt one of my 3 embryos had stopped developing, but the other two were good. Would I like to put one or two in? Given my age, they recommended only one, so I went with that, and opted to freeze the second. So it was back into a less comfortable set of stirrups, and they walked me through embryo transfer which was not comfortable (speculums are not fun) and one was put back in.
Which brings me to now. I'm on two Cyclogest pessaries a day (progesterone) which aren't as awful as I was expecting, although they are making me more tired than usual. I'm back to work on Monday, which won't be fun, but was always going to happen. Then Friday is my test day.
Exciting to hear you're also thinking of going it alone. I don't think my PCOS really counts as a serious fertility issue - women with PCOS are able to conceive naturally, it's just harder to time it, or at least that's my understanding. It has been a costly experience thus far, even with the egg sharing (which has helped a LOT!) but I figure it's money I haven't spent on dates and weddings and all that sort of stuff, so whilst I am aware it'd be different if I had a partner, I don't think that's a really big deal.
Good luck with your journey. I wish you all the best.
