Should I worry

My cycle came 6 days early and I know not too depend on a app, but my cycle would be one day off from my app. So, I started have brown spotting. That has never happened before it would usually be red spotting when my period comes. I also did have cramps with my cycle, but this wasn't too bad. It just bothered me a little and I never had headaches or body ache with my cycle. Current my head still has a dull ache, but it could be the hot weather. I also notice I go to the bathroom a little more. I never go twice at night, I would go once. I'm not trying to have baby, but if one does show I won't be mad. ❤❤❤ I'm just curious because I did hear of Implantation bleeding. My cycle did go from brown to red, but it wasn't too red. I treated it like it was my cycle. Also, the week before I got my period, I never had breast tenderness, but that night my breast hurted soo bad. Like someone punched me. I thought I was laying on it, but even after I adjusted my self it still felt the same. 😞 so idk should I just ignore it or make sure?
