issues with lh surge test

Rach • Mommy to a 7yo 👧🏼 and new born 👶🏼 boy

has anyone have a positive 4 days after their period. I should be ovulating this week, Saturday to be exact. normally I get darker lines going up to ovulation, normally starting about 3 days before. I am getting 1 line, not even faint second. My period was 1 day. I've gotten negative pregnancy tests and have zero signs of that or ovulation coming.
