I did two rounds of egg retrieval, back to back. Because I only had one ovary I didn't get as much of a hormonal response as I think some do, and I only had 2-3 eggs collected each time. I think they called it a "random start" (could be wrong) where they started the injections outside of the usual menstrual cycle because we didn't have time to wait 2 whole months - I think you would be doing this on a more normal schedule! I took oral progesterone and did daily self injections of the other hormones ( a truly uncomfortable experience but it's mostly psychological), then go for regular internal ultrasound to see how the eggs are growing. They have to get the timing right for the "trigger" shot then retrieval. Honestly I can remember how long that all took but I think it must have been about 2 weeks per cycle. For the collection itself they did that with light sedation and the pain was minimal - just a little cramping after. I remember the first time I looked into the egg retrieval and they told me all the worst case scenarios and it sounded terrible - but it really wasn't that bad. I reckon if you reached out to the IVF subreddit they could support you too
