So I have been TTc for 3 years I have PCOS and have just had my 6th round of clomid. When I first started trying my cycles were a pretty consistent 32 days long. Over the last year or so they have shortened to a pretty constant 28 days. For my first 5 rounds of clomid my cycles were still 28 (and one 29) days. Around cycle day 26 this cycle I started to feel bloated and crampy and I thought AF was on her way, but she didn't come. I held out and took a FRER when I was on day 30, it was a BFN. Over the last few days I have had creamy, almost sticky CM, but no other symptoms. Today is now CD33 and other than the CM I have no symptoms and no sign that AF is on her way. So my questions are: 1) I can't be pregnant can i? FRER is one of the most sensitive tests so if a was it would have showed up, right? 2) Can clomid delay your period even if you are not pregnant, it just seems weird that af is a no show when i am usually quite regular. 3) Any ideas if something else could be going on?
