Dotted crosshair line ???

Bec 👼👼finally our 🌈

Can anyone please tell me why my crosshair line went from solid to dotted this morning 🤷🏼‍♀️ does that mean I may not have ovulated when I got my positive OPK on CD15 and O on CD16?

I got bloods done yesterday to see if I ovulated but won’t get results back for a few days and my temp dropped this morning.

❤️

Any advice please
