I experienced light spotting the week after ovulation, towards the end of that week I had consistent 3 days of light spotting and one day of a heavier spotting of dark brown then nothing. With the spotting there was only brown with maybe a couple patches of red throughout the 3 days. I am now 6 days late with no af. How do I track my fertile days of I didn't get a real period?? Tests on day 6 is negitive though I was hopeful even experiencing breast tenderness, nausea and cramping... What do I do??
