AF a week early

Melissa

Glow said I would ovulate on the 8th so hubby and I had sex the 6th. Tested for ovu starting on that friday(5th). Started my period today and when I put it in it showed I was supposed to ovulate on the 4th so we missed it😭

Does this make sense to anybody? Has anyone ever experienced this situation?

My fertile days start Saturday and ovulation next weekend. Hubby is only home on weekends so hopefully this is our month!
