Advice maybe pregnant?

About a week ago I tested and got a positive then started having what was period bleeding except the bleeding was shorter then my regular period it was 5 days my normal period is 7 days. I tested on the last day of bleeding on Sunday and the test was again positive. Not much darker yet a little darker. Today I tried testing again but had a faulty test and took a digital that said no-. Now I’m left confused because I keep feeling like I’m pregnant but not sure about the test or short period.
