That's awesome your doctor is going to help you like that. I pay out of pocket for IVF and it sucks! My doctor did give me the meds for my last cycle which was helpful. I hope the drug companies give him some more samples!
Anyways, I have pcos. I'm probably not the one to help you as we have some other problems as well, but I'm around if you have questions. I think you are a great candidate for it especially if you are getting such a good deal! Your age is a bonus and the fact that you have a child shows you can get pg!
You mentioned af and gonal-f immediately following it. Most women have to take bcps for a short time and then some have to take something for suppression before they start stimming. Did you doctor mention any of that? They like to shut everything down and start from scratch with the hormones... more control, I guess.
Good luck. If you have any questions about the process, feel free to ask me.
