Cory, I'm sorry this isn't your month. I'm right there with you -- my temps took a nosedive this morning and AF is due tomorrow. On to cycle #6, I guess. We really nailed it on the timing too, so I had my hopes up
I don't know what to tell you about the wacky timing of your spotting. It doesn't make much sense. But with the red spotting last night, I'd probably start again with cycle day #1 as of yesterday. You didn't say if you had tested... is it possible you had a miscarriage? Hang in there. I know it's frustrating for this to take longer than expected. We go through our whole lives trying to be so careful because everyone tries to tell us how 'it just takes once', but then when we're really trying it's disappointing when it starts to become apparent it's not that easy.
You really may want to start charting. It will start to give you some more insight about when you're really ovulating, if your spotting is really AF, etc. It also makes it easier to get feedback from others about question you're having about your cyles. You can get a free account at fertilityfriend.com. Of course, charting can also be addicting and you might start to obsess like the rest of us about every little dip or rise. At least it helps to pass the time, right? Good luck this cycle!
