Is it possible that sex can interfere w/ ovulation lines and how dark they are ? Im asking because glow originally said Jan 7 was an important day for me and ovulation was Jan 8th I started fertile window 1/2 and started opks 5 days into my fertile window and I haven't got a straight positive opk test 1/8 was the closest but everyone said no I'll post the test below and tonight me and my fiancé BD last day of my fertile window on glow and I have ovia my fertile window was 1/4-1/9 and I'm about 4 days after My fertile window and after I took opk and I'm thinking I finally got a positive one but could sperm had interfered?
