So, I had my period August 5-8.(four days is normal for me but was two days early

). 6 days later I’m still spotting. For the first few days of spotting it was like a very very light period and now it’s pink tinged discharge. I also thought I had started getting auto because the other morning I woke up and had the urge to pee several times and it was burning. I started taking cranberry supplements and that feeling went away until today. Yes I know I should go to the doctor but as of right now I don’t have health insurance until next month so I’m coming to you ladies for advice. Could I be having a tubal pregnancy with no symptoms? Or just be pregnant with no symptoms? I took a test on the 8th and it was negative... I don’t know what’s going on, help please

And here is a picture from today of the spotting
