more than 6 cycles of clomid?

Brittany • TTC 2nd child, on Metformin for PCOS

anyones dr let them do more than 6 cycles of clomid? I'm in my tww on my 6th round now and was curious about what to do next if it doesnt happen this cycle. so I asked and she said I could just continue clomid. I have ovulated the last 3 cycles.. I've heard that it can cause a thickening of the lining, but she said as long as I'm ovulating it doesnt cause a thickening.. just wondering if anyone else has done more than 6 cycles? and any success?
