Is it possible to ovulate twice in one month, at different times?
Normally if you happen to ovulate twice in one cycle, it happens in the same day. Once ovulation has occurred, your progesterone levels rise (which is what a spike in temperatures measures) and ovulation is no longer possible. So I don’t think the increase in CM is related to ovulation, and because you were using OPKs, you can count CD12-13 as being pretty accurate, which means that AF is due about 14 days later (CD26-27). Many women get increased CM in the luteal phase, but normally it’s just an abundance of ‘creamy’ CM, not ‘egg white’ CM, and is therefore not fertile. Good luck with waiting to test!
