DId you manage to get an answer from your FS. I would assume that you can came straight off the pill and onto clomid, as it will help you make the hormones you need to get your cycle going. It does take some people months to get a normal cycle back after the pill, and if you have PCOS might take a while.
I used clomid after coming off the pill to get me Oing more regularly, but I had been off the pill for 6 months...
I think you are right though to check with your FS.
Good luck with your cycle!
