Tara, I replied to your post in obsess+test tread, and, um, edited cuz I was having a milk-brain moment... :P
(I'm a brand-new charter, so forgive me if this is a silly ?)
gottecat- fingers crossed for you!
SoCaliMommy- fingers crossed for your O to lead to a sticky LO.
tropacana- Just to clarify your question- are you asking if you can O BEFORE your period (like, will you O before that first ppaf), because, yes, you can, although it isn't a certain thing. Some women's first few ppaf's are anovulatory, while some O before ever seeing a ppaf. In my understanding, the older your nursling is when you get ppaf, the more likely it is that you O'd first.
zwitterion- gosh, I'm sorry for your confusion. I'm such a novice that I can't really make a good guess at your chart, but I know other pp have suggested it- is it possible your coverline isn't right? Or is there any other environmental reason you could have had low temps? Hope it gets sorted out for you in the next few days.
