have I ovulated??

Amber • Husband and I have been ttc #1. Cant wait to have my own little family. ♡♡
I am new to charting my bbt and I am trying to fund out if I have "O". My period started on the 20th and ended the next day, but glow said I was supposed to ovulate sometime during the same week. I had EWCM on 6/28. but that is the last ive seen of it. so can someone help me out that knows about bbt charting please.
