Congrats on qualifying for funding and making it to the waiting list! 18 months is a long wait, but it gives you lots of time to prepare and find answers to any questions you may have.
When I did IVF/ICSI, we did the "short" protocol. It was actually only a 3-week process. I started "stimming" (taking hormones to stimulate my ovaries) on day 3 of my mentrual cycle. By day 14 or 15 I had my eggs retrieved, they were fertilized, and 5 days later one embryo was transferred back to my uterus. Unfortunately it didn't work for us and we are still on the fence as to whether or not we will try again, but if we do try again our doctor has recommended a longer protocol. Not the 8-week protocol (that involves taking the birth control pill for a month before stimming, etc). The protocol suggested for us is called "down-regulated" protocol which involves taking a hormone to rest the ovaries for a week before stimming.
To be honest, most of the time throughout our IVF cycle I felt pretty good. By day 8 or 9 of the cycle I started to feel bloated from all the follicles that were developing inside me (I ended up with 23 eggs). The egg retrieval was uncomfortable and slightly painful in the moment that it was happening, but the pain only lasted for 30 seconds to a minute, and went away as soon as they were done.
The only hormone that affected my blood sugars was the progesterone which is given after the egg retrieval. It's to prepare the uterus for the egg transfer and to encourage the embryo to implant. I had to take about 25% more insulin than normal during that time. Rachel, another woman in this group who also did IVF mentioned that she had a similar experience with progesterone. I was prepared for it though because I know that my insulin needs naturally increase after I ovulate each month (which is when progesterone increases in the body).
Although I don't know of any resources specific to diabetic women (unfortunately it seems we are a minority - either that or not enough of us are talking about it), I used to frequently follow discussions on www.ivf.ca just for general IVF info. Although mostly Canadian women use the site, the IVF discussions are pretty generic and apply to anyone doing IVF. I found it extremely useful during my cycle.
Good luck on your journey, and if you DO find any useful diabetic-related IVF info, please feel free to post it here! I am sure many of us would find it useful. :)
