Looking for advice!

New to ttc! This test was taken 7 days before my predicted period starts. (First response test, not from Walgreens) I think I can see a VERY faint line, but my husband doesn’t. Took another test the next morning (6 days before predicted period) and didn’t see anything. If you do see a faint line in the photo, is it normal to get mixed results since it’s still early? Thanks :)
