I have no idea what's going on. TMI

Honestly, I really don't. This might be long. My body/periods are so weird! I've been pretty regular then after my miscarriage in March my cycle got weird. It got back on track for a little bit then last month I had spotting for a week before my period started, but I had all the symptoms of AF. This month however, I was due for AF on 10/3 and I started spotting the 28th. First, I'm NEVER early, if anything I'm always late. I haven't had ANY symptoms besides sore breasts and nausea. Barely any cramps compared to my usual agonizing ones. And when I do spot, it's brown for a couple days then period. But it was brown then immediately red then nothing, then repeated the next day and barely anything today but still brown and gooey mucus red. I have no cramps and it's not really getting heavier, but all my tests have been negative. Idk if I just have another weird period or what.
