Hi, granted I am self-diagnosing here - I have a twinge of pain coming from my left ovary which seems to match up with the symptoms of a corpus luteum cyst. It would make sense, as af is now several days late (because it's still making progesterone) but I'm getting BFN on all my tests. I think it's because I took b6 this month... I'm totally out of whack. Does anyone know how long it might take to break down, so I can get back to the business of ttc? Who knew I would actually be wanting af to arrive on time! Lol.
