Faint line test question...

Kylee

The past 2-3 days I have taken several pregnancy tests. The first one had a faint line and I had several negative between another one with a faint line. I know a faint line and then negative test could mean early loss but I had another faint line and I am 4 days late on my period. Is this normal? Anyone experience this? Should I just chill out on the tests for a couple of days? Thank you in advance for any and all feedback/advice!
