8 days late, help!

Amy • Married to my High School Sweetheart 💕 👶🏼 IUI #1 success in 2019

8 days late for my period and these are my ovulation tests since Monday... I’m beyond confused! Pregnancy tests have been negative since 12 DPO.

I had egg white CM on Friday, white creamy CM yesterday, and watery CM Monday & Today. I think there many have been a drop of blood in my underwear today when I woke up but none when I went to the bathroom. Any ideas? What should I do?
