IVF & PCOS

Lokelani
Anyone know the steps for IVF?  i don't know the lingo all to well so I can really understand everything on here but I've been on metformin, clomid, IUI 2x and nothing worked! I'm thinking about doing the IVF after I get married in September but wanted to know the timeline and how long before I should prepare... Idk any information would help thank you
