My period is 8 days late. on the day of my expected period i got light spotting and now am having a small amount of light brown discharge mixed with light pink. i took a pregnancy test, but it came back negative. is there any way that my test was wrong?

Repeat: From time to time, the ovulation was later than usual and the pregnancy test shows a false negative result. Repeat the pegnancy test in 1-2 weeks.

Blood test: You may repeat the home test in 4-5 days. Use first morning urine and follow the instructions for the test carefully. Alternatively, you could get a blood test for HCG level, that would settle the matter sooner.
