So the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> predict that my ovulation day was yesterday on the 10 so me and my boyfriend have be putting in work 3 days before so when I took the ovulation test a clear blue test it had one light pink line and one dark line so that means I wasn’t ovulating so help me understand please ?
