Faint line early?

Natalie

I have been taking tests and getting positives from early response tests since 2 days before my period. But now I’m 2 days past my period and the normal tests that aren’t early response still take a few min for the line to get darker. Then it’s visible. But just takes awhile to get there. Could it be because I’m still early? Or should I be concerned that it takes so long to get a real visible line. Just curious thank you!

** also doesn’t appear like it’s getting fainter, just still takes awhile and I thought it would take a shorter time and be more visible sooner now.

Please help! Thank you 🙏🏻
