I suppose it depends on what/if any additional testing will be added. There will also be many other factors such as how you react to meds/cancelled rounds/follicle count etc.
My timeline is below, I hope this helps :)
Round 1
First lot of meds started end of April 2022, dosage was too low so that round was cancelled mid May 2022. Needed to wait for a bleed before starting next round (some clinics like 2 bleeds between cycles)
Meds started again end of May-Mid June 2022, collection end of that month with transfer in July 2022. That resulted in a positive but miscarried at 8 weeks.
Round 2
Used the frozen embryo from above collection, meds started end of November 2022, knew within a week this had failed so stopped progesterone. (obviously a larger wait time between due to the miscarriage, they wanted 2 bleeds between miscarriage and the new cycle)
Round 3
Fresh transfer, meds started early February 2023 with the transfer taking place end of February. Knew within a week this had failed.
Round 4
Frozen cycle using above embryos, meds started end of June with the transfer mid July. Resulted in BFP and now 25 weeks pregnant :). I had additional tests in between cycle 3 and 4 which looked into possible reasons for implantation failure, these went missing so I think I waited about 8 weeks for the results, the treatment could have been started sooner had the results been received sooner.
Overall time scale from round 1 to round 4 was approx. 15 months.
Don't forget to take the number of follicles into account, 1 cycle is not classed as complete until you have used all embryos per cycle, 1 collection could result in 3 blastocycts so that cycle alone could take maybe 9 months etc unless you bank these.
Good luck.
