Ok, so first of all, I've put my BFP in FF but it is still estimating my next fertile days and not telling me a due date. What the heck? Perhaps I had a VIP Membership for my last BFP but I swear it changed!
Also, I'm unsure about how to calculate due date. Because I O'd late this cycle using my LMP won't really be accurate. If I use the day FF says I O'd (Sept 18 - CD 19) then it puts my due date at June 11, 2013. I honestly don't think I would have O'd on CD 19 though because I got my + OPK at 5pm on CD 18....does that make sense? I don't know. That would make my due date June 12. Thoughts? I guess it doesn't really matter. It will probably get changed a bunch of times.
