Hmmm, I don't know, MzSwizz. If you did O a couple days ago, it would probably be too soon for IB, but anything's possible. I'm the queen of random spotting/bleeding, so I just try not to think too much of it. I had 2 days of spotting- actually while we were out of town of course. I chalked it up to being stressed out the first day and I hadn't even marked it on my calendar. Well, FF now thinks I O'd. I changed my CD35 temp because that was the wacky one and I wasn't sure which temp to go with anyway, so I went with the higher one because it matched my 4 a.m. temp, which was higher than usual. I already had solid cross-hairs, but for CD36, and I really thought if I had O'd it was CD34, which is now what my chart says. I'm not convinced I O'd but those solid cross-hairs do look lovely. So after today's temp and my cross-hairs moving, I thought I'd better add the spotting, and it was possibly 6 and 7 dpo, with my temp jumping up today at (maybe) 10dpo. I hate it when my chart gets me all hopeful lol. If I did happen to O on CD34, then I BD 2,4, and 6 days before O. If it was CD36, add 2 days to all that. If it was yesterday, then I BD on O day. Today's temp completely shocked me. It was taken a bit later, but just about all the open circles on my chart were taken within 10 mins of today's temp, so obviously the later temps don't automatically make my temps higher... and not this much higher.
Anyway.... Grrrr... Now I seriously want to go get an hpt lol. I'm not going to. Ok well I'm going to try not to. I'd like to just wait it out and see what the next few temps look like.
