5 days late!!! Please help!!!

Dear all,

My period is 5 days late. I've done a pregnancy test yesterday and it's negative. I stopped using the pill 2 months ago. My period was on time last month. My cervix is very low, open and I have creamy and thick lotion like cm. My bbt went up high after my ovulation. I have breast tenderness and suffer from a headace, constipation and some cramping. 

Could I still be pregnant with my current cervix position and test result?
