I'm a long time lurker, but am so confused about this cycle I needed to post. I'm on cycle 3 of 100mg clomid monitored cycles with an RE. The first 2 cycles I responded too (although didn't result in bfp), but this cycle is wonky. I went in CD12 and had a 14mm follicle, then back today and nothing larger than 11. He thinks it's possible I could have ovulated (waiting on bloods) but what the heck?! I've never ovulated before day 17 before. Ugh! Any idea if its possible to stop responding to Clomid after have previous positive results?
