Does Line Progression mean anything??

Crystal

I got my BFP 5 days ago. I am now 13 DPO (AF due tomorrow) and continuously keep POAS because I am so nervous about something being wrong.

For sanity purposes I know I should stop but does line Progression mean anything?

This is yesterday's line

And here's today's, just a few minutes ago.

Help me become sane again PLEASE!!! What do you ladies think?
