AF and ovulation help?!

Tiffany • Mother of a baby in heaven 👼🏻 and my beautiful rainbow 🌈 baby 👶 TTC my next bundle of joy 💕🤰❤️😘

So originally I was suppose to start my period on the 17th and by a positive OPK result, I ovulated on Thursday the 7th. When I added in the results, Glow moved my period back until the 21st. My periods are pretty regular so my question is, does this effect my period?
