Help. Idk what's going on with me yet

So I had my period from Oct 28-Nov 2. Everyday since(today's the 6th) I've been bleeding, but weirdly enough, it's only when it gets dark outside. It don't last long, usually stops before I go to bed. My breasts are still a bit tender & I'm bloated AF(I look like I did when I was about 3-4 months preggo with my kids) Of course I plan on talking to my doc next visit, but wanted to see if anybody else has experienced this. Not sure it this would matter, but I'll be 34 in Jan, 105lbs & have a 13 & 10yo
