Tracking your fertility

Katryce

Do you ovulate at roughly the same time every month? Give or take a couple days up to a week variance? I had EWCM moderately CD 10-16 this month,... and ovulated on CD 30 last month. I read that your body can do a 1/2 LH surge before you ovulate. So maybe thats whats happening to me? Im now testing with OPKs on CD 20. As to not be wasteful.
