Late, negative tests.... Still chance of being pregnant??

Has anyone been really late, negative tests but still been pregnant?

Af was due on the 3rd may still no sign of it done tests and there's negative but having pregnancy symptoms ie bloated, painful boobs/nips, tired, feeling sick on and off, consterpated, light cramping, matalic taste.

Went to doctors Monday she got me to do a wee sample so she could send it to the lab to test for pregnancy ( still waiting for results)

I'm so bloated I actually look pregnant

Iv been pregnant 2 times before 1st time was 5 years ago wasn't trying and didn't find out until I was 7weeks.

2nd time was last June found out before missed period (was ttc) but miscarried days later
