I too have PCOS but am extremely lucky to have two kids. My cycles were all over the shop when TTC #1 and it was by sheer luck that we caught the one and only egg I popped out in over 14 months. After I gave birth to my DD it seemed to "wake" my ovaries up and I was suddenly regular. We used condoms as contraception and it took us 6 months of regular periods to TTC #2. After #2 I I had a mirena put in. Two weeks ago I had that taken out so I'm waiting to see what my cycles are like now.
I was about to be commenced on Clomid when TTC #1 & #2 but found out I was pg the night before I due to start a Clomid cycle.

Sorry not much help but I wish you the best of luck. You weight loss is fabulous. Every gram will help. Keep up the great work.
