First infertility appointment this week. What to expect?

Bryony

I've got my first infertility appointment tomorrow. I came off the pill September 2022 and got diagnosed with PCOS in July this year. What were your experiences (I'm in the UK)? Did they start you on treatment straight away, or do they want you to have a period first? I'm hoping to get letrazole and would obviously love to start it ASAP.
