So, for those you who are wondering (so, was this a false surge? When did Decaf ovulation?)
Apparently, the day after the date when I told someone there’s no way I can ovulate by then is the day I ovulated this month.
On the plus side, I’m going to get my period by Halloween.
The minus side, this month is obviously out for trying. At least we didn’t waste sperm trying on CD 13.
