Could I be pregnant or just a SUPER light period?

Okay so the father of my child came in me WITH OUT my permission while we were drunk and had a hook up. He literally wanted to get me pregnant so he came in me seven times and was acting like he wasn't coming and kept telling me that it was me that was getting wet for him not him cumming..... After we were done he admitted to it all and I havent seen him since then (he doesn't try and see our son unless I beg him too and before this occasion haven't seen our son for eight months. Yes I know I'm terrible for having sex with him but I grew out of the system and I really want led my son to have a family even if we aren't together and having sex with him was the only way to get him to see his son and it made my son so happy to see him) ANYWAYS I am supposed to start in three days but I've been having this weird stuff happening lately..... I pee and a little bit of blood comes out but when I wipe the tissue is not bloody... And I only bleed one pee to two pees a day... but again the napkin is NOT bloody when I wipe... The reason I ask could I be pregnant was because I bled in this exact way when 9 weeks pregnant with my son. If I'm pregnant I'll do what I need to to bless the child but I'm wondering could it be just a SUPER light period?!?! Like has anyone else bled like that and it be a period??? pregnancy tests literally don't work on me and I have to get my blood drawn.... THATS AN EXPENSIVE HOSPITAL BILL THAT CAN BE AVOIDED! Please let me know what you think before I decide if I need to go in! Am I pregnant or is it a SUPER light period?!?!?
