You could temp for a cycle and find out.

During my LP as my progesterone is dropping I also tend to get a lot of CM, but not EWCM. Maybe you are ovulating early too?

I finally got af back at 9 months postpartum. Both times, I have had DAYS of sore nipples and ewcm, then shortly afterward, my cycle begins. Can symptoms of ovulation continue days after it happens, or is my luteal phase ridiculously short?
