Missing one dose of your PCOD tablet and taking the rest at different times is a very common reason for a delayed period with light spotting, since it disrupts your hormone pattern for that cycle. A faint, unclear line that sits oddly compared to the C line usually means the test result isn't reliable yet, not a clear positive.
Next Steps
Repeat the urine test after 2 to 3 days using first morning urine, or get a blood beta-hCG test done for a clear answer either way. Keep taking your current tablet as usual unless your gynaecologist advises otherwise.
Health Tips
Please see a gynaecologist soon to confirm the result and review your pill schedule. Go in sooner if spotting turns into heavier bleeding or you get pelvic pain.
