Faint positive yesterday... Negative digital today

Brandi

Hey ladies. So I am 7dpo today and yesterday I took a test with fmu and it came back with a faint positive then through out the day it eventually faded and said negative which is weird but it came up positive first within the time frame. This morning I took a digital with fmu and it said no 😣 what are your thoughts? Does it just take longer for a digital to pick up the hormones? I also took an ovulation test yesterday and there were two lines!!
