Am I pregnant because my body is messing with me

alia

Took a pregnancy test Thursday (9/28) because I had a lot of pregnancy symptoms and I was cramping with very very little and I mean if any light pink blood but I got a negative. Following Friday I took another test in the morning and got a negative again. That day I started bleeding and assumed I started my period because the blood was darker and I was getting more of it but it still wasn’t my usual period. I also started taking birth control this day at night and the next day (Saturday) I was still bleeding but I noticed most of the tampons I was pulling out felt really dry and had some blood on it but parts of the tampon were still white which was weird but I took my birth control again that night and today I have no blood whatsoever. I have very very veeeery little brown discharge and some light cramping but that’s it. I have yet to take a test again but should I or should I just go to my doctor or is it not worth it to take a test? I don’t want to keep taking the birth control if I’m pregnant but also if I’m not I don’t want to stop taking it. Any response back would be so appreciated because I’m kind of stuck here.
