How late before bfp

Danielle • Mommy of 3 girls ages 12, 6 and 4

Ladies I have very irregular cycles but not normally this long . I’m on cycle day 37 and according to glow 3 days late but they may not be the case . I thought I ovulated two weeks ago according to temp dip and opk but I could be wrong . I’m starting to think I’m out this month 😩 how late were you before you got a bfp? I keep getting indents or weird lines then negatives then indents the last week on different brands . Today for a Bfn 😩 how late for af before you got bfp ?
