Ovulating

Joddie
Hi im just curious i have tracked my period for about 2 yrs now with Glow. it has always been on point maybe a day head or a day slow. My question is every gynecologist ive been to says u ovulate around the 14th day of ur cycle starting from 1st day of period. but on my tracker for my period it always have me ovulating at day 10 of cycle. i feel like this is a mistake cuz me an my fiance have been trying for 7mths no luck at all. could the <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> be wrong.
