Hmm, I don't have access to your chart, but I'm really confident in your temps listed in previous post. If that were my chart, I'd call that an O on the day before 36.4 :dance: I would also call it a 'slow-rise,' which may or may not be indicative of anything.
TWW = two week wait. Essentially the luteal phase, i.e. time between O and (expected) AF, the phase that is of consistent length (two weeks??) This is the time when people who are and want to be very clued into their body may notice symptoms that turn out to be early pg. They could just as easily turn out to be PMS symptoms, so it's always a bit of fun to see which way it goes. Most people on BB try to hold off from testing for pg with HPT until the end of TWW or the day that AF is due (more/less than 2 weeks) or after. But some of us are eager!
I should also say that it sounds like you're doing really well with interpreting the bbt information you have. After a few cycles, hopefully a pattern will show and you'll know what's 'normal' for you.
