I was diagnosed with secondary infertility in June 2014, which was a huge pill to swallow. We managed to get our much waited BFP in Feb 2015...but 10wks later i was being taken into theater for a d&c for a missed miscarriage after hearing beans heartbeat 4wks before hand. Ever since my cycles have slowly started to become more on the regular side of it all as before af would range from 17days to 47days. For the last 5months ive been spot on 28days and i would actually get excited..i know, stupid to get excited when af showed but it told me i had ovulated, even though i was heartbroken that the witch showed up, i knew i was getting closer to having a successful pregnancy without meds....that was until this month...af was meant to show her ugly head on wed 3rd and nothing...so i was getting excited...thinking is this finally happening again...so i waited the day and tested on the 4th...my heart sunk....BFN!!! I honest dont get it...fast forward to today the 6th and still nothing...the only thing i can think of is im not regulating and i O'd late (from cd19 onwards) making me as of today only about 10dpo?!

When my cycle was irregular id O between cd16 and cd20...

Please any ideas or experiences would help put my mind at ease.
