Yay for proper Af!! A dose of 75 is still quite high to start. I started on 50 for my very first cycle and after a few weeks and increases finally ovulated on 92. For this cycle they started me on 66 and after a week have moved me up to 82. I go back on Monday for another scan. I also did clomid and did cycles on 50mg, 100mg and 150mg all of which failed to even get me anywhere near ovulating. I don't have any insulin issues either.
Hopefully as you are starting at that dose it won't take as long for your little follies to grow!! When is your first scan?
