10 days missed period and Negative HPT

Shonna

I’ve been trying to get pregnant for 3 years and found out I’m diagnosed with PCOS 2years ago. No luck with clomid or femara. Now I’m giving my body a break and not taking any kind of medicine except prenatal + folic acid. My last period was August 1st and I’m 10days late for my period and got 2 negative HPT. And I don’t have any pregnancy symptoms. Has anyone ever had a negative HPT but ended up being pregnant?
