Antagonistic cycle

Apparently that’s what it’s called and that’s what I’ve been recommended. I’ve only had two failed IUI but moving to IVF now. I’m aged 36 and in a same sex relationship so my wife and I are using donor sperm through a fertility clinic. I wanted more goes at IUI but it wasn’t allowed. I’ve read all the leaflets that came about IVF but would love to hear others experiences of what this is going to be like. I know it’s a lot more involved than iui and a lot more expensive.
