Dye run or positive

Oh lordy so this is my second test and they both look like this. It's so hard to tell what's happening. I have a 2 month baby and well a lot has happened in the last month I got my first period my milk supply took a dipped hubby and I had sex before I got on my birth control I've had nausea and somewhat light headed this could easily be the birth control kicking in or it could always possibly be a baby with unprotected sex(even though he didn't finish inside) what are your thoughts.
