dont give up and talk to your specialist. It may be a good idea to move up to the next stage. I was told that just the drugs and times IC isn't a big cost difference between that and IUI as IUI is rebated at higher rate.
im 29 and my husband is 38 we are healthy and I have a 6 year old daughter.
i also have PCOS. We have been ttc #2 for 2 years. We did 3 cycles of clomid and 1 cycle of IUI before our specialist moved us up to ivf (antagonist - short protocol).
i was really upset about doing ivf but you know what? I'm glad I'm doing it now because its greater chance of it working and getting us closer to the goal.
Dont be disheartened as hard as it is just keep positive.
i have been doing Accupuncture which is fantastic and taking royal jelly.
