Backtrack: Had sex (protected/ used a condom) Feb9,2019

And then I had my Period march 4 it was light to medium Flow, I can fill a pad and have to change about 3 times I think. Then now I still havent got my period. Question am I pregnant last month?

PS: took a pregnancy test last march 12 and it came out negative can this be false negative?
