Pregnant?

Madeline • 24. Single mother. ✨
Okay guys, doing a blood test tomorrow with my doctor. 
16dpo. 5 days late. I've taken three tests and they've all been negative. I usually have a 27 day period on the dot. My diet has not changed, I'm not stressed out or anything. 
My cervix is very high I could barely reach it. And I have a creamy white thin cm. I am having very minor back cramps and lower abdominal cramps. And they just pop up and go away. 
What do you guys think? Could I still be pregnant? I know some women have a hard time with hptests. 
Please give me your opinion. I'm dying over here 😂😂
