OK, so I thought I would update where I am at for those who may have similar situations in the future...

I am on CD 30. AF is now 3 days overdue. Since last Thursday I have had sore swollen boobs and slight cramping on and off until yesterday. Yesterday I had really light brown discharge (only when wiping) and loads of wet CM. I've been peeing like crazy and felt mildly queasy. I've been tired but not exhausted and have been sleeping only about 6 hours and I wake at 3am and can't get back to sleep. And my dreams have been incredibly vivid and weird... And no AF to be seen!

So I am going to wait until CD 35 (one week overdue) to POAS, give myself a few more days to have a period even though I have never had a cycle this long, I haven't had any stress or sudden changes in diet and exercise, and my cycles have been 27 days long for the past 6 months (I looked back and double checked).

Chatted with DP last night and he is pretty excited about the possibility, even though we weren't trying at all. And I have been trying to figure out when I O'ed... I guess it doesn't matter really
