What does this mean???

Pia • Miscarriage with my 4th, trying to conceive baby number 5
So AF  ended yesterday. Since this is my first time <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> I took a test yesterday and this is what I got. The top one was yesterday evening around 5. The 2nd one was this morning a little after 9. The other 2 were around 1230 this afternoon. I was surprised to see any lines considering AF just ended. Could I be ovulating sooner then what I thought??? Just started letrozole I'm on the 3rd day of the pill. Any comments would greatly be appreciated. TIA
