Hi Ellas mum,
I was diagnosed with PCOS after coming off the pill to ttc#1 and had no periods for 6mo. I went to the GP and got a referral to a FS. She gave me a script for clomid (first dose was 50mg and did nothing, 2nd cycle i had 100mg and got a BFP).
I went back to my FS when we wanted to ttc#2 4months ago and have been on 100mg clomid each cycle since and only BFNs so far!
I didn't chart at all, but I'm going to start for the next cycle, so i'm sure you don't have to chart before seeing a FS. But I guess the more info you have on your own cycle the better.
