Hi Hopeful25! You sound almost exactly like me and my husband - same ages and PCOS. Fun fun fun. I was PETRIFIED during my entire cycle. My doctor put me on almost no medication and threatened to half it almost every other day. I was only taking 75 units of gonal-F (same as follistim) and 75 menopur. I thought she was going to mess up my cycle and I would end up with nothing because she was so nervous about OHSS (which I was definitely going to have and we avoided by doing a lupron trigger - but that makes a fresh cycle impossible).
First, being on a low dose was totally and completely fine and amazing! I had so few of the crazy side effects. I just fell asleep all the time - I slept probably close to 14 hours a day! Also, because of the super low dose, I ended up having my retrieval 4 days late (so 13 days on active shots before the trigger shot). But because of our young age (which is really unusual in the IVF world), we ended up with 28 embryos on day 5. 47 eggs retrieved, 31 mature (with PCOS and tons of eggs there end up being a lot of immature eggs too), 23 divided by day 1, but then on day 3, we found out that all 23 were growing nicely and another 6 that they thought had not fertilized had started to divide! On day 5, all 23 plus 5 of the 6 late-bloomers made it. Doing PGD, so they are currently being tested and we'll find out how many usable ones we have in a few weeks.
I hope this makes you feel better. Your success rates should be amazing! I can't even tell you what a blessing it is to have age on your side.

And PCOS (if well monitored) just means more eggs and more chances!
