I’m a little confused. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility apps</a> are saying that I ovulated yesterday. Some say I ovulated today. But I’ve been taking ovulation tests yesterday and today. I did forget to take it Saturday. But the ones I took keep saying negative. My discharge shows that I’m in my fertile window and I’ve had discharge since Thursday. I’m very confused as to why my test keeps saying low ovulation or low fertility. Today’s fertility test was actually lower than yesterday. Can someone help ?
