I ovulated last week monday 12/13(sure because i had follicle tracking) got period today. this is strange ! ive also read online its 14days post ovulation period comes. i take prenatal gummies, coq10 & one a day immune support daily. what is happen?

If this period is 4-5 days shorter than the previous period and assume your follicle tracking is accurate, you have a short luteal phase this cycle (less than 10 days). Otherwise, your method of follicle tracking is inaccurate if this cycle is not shorter compared with the previous cycles.

"Follicle tracking" can show when a "follicle" present is no longer detected by ultrasound. The "follicle" is identified as containing a viable egg, but many so-called "follicles" are simply ovarian cysts, so their absence does not mean ovulation has taken place. True ovulatory follicles rupture to release an egg, and if pregnany does not occur, a "real" period occurs 14 days later.
