Clomid or fermara treatment cost

I’m February I had all my testing done along with my husband. There is no issues with either one of us, the only thing she said was that my cycles are long making ovulation occurring at different times. Making it a little harder to pinpoint ovulation. We have been trying ttc #2 for 3 1/2 years now. Just started my period and am really starting to think about doing the treatment. I’ve heard better things about Femara than Clomid. She wants to do Clomid 3 months then switch. It’s 500$ for the treatment. Should I tell her I want to try Femara first? Any recommendations or advice? I really want this second baby 🤞🏼 and if I’m spending 500$ each time I want to make sure I get the best out of it. Also how much does it cost you ladies for this whole treatment?
