Ovulation Right After Period?

Amanda

Everything I am reading is saying that ovulation is approximately 12-16 days after your period. Why am I ovulating at approximately 3 days after? I’m trying to learn by the average woman’s science but I’m having a hard time getting the basics when mine comes so quickly.. Does ovulating that close to your period signal PCOS? Is this not a good sign? I’m in month 2 or 3 ish for TTC now

*I track using OPKs and pin point ovulation by testing and ovulation pain*
