TMI PICTURE Does anyone bleed mid cycle after baby?

It's happened a ton of times to be now. My periods returned at 4 months and have been between 30 to 37 days apart each month which is actually really regular for me lol but normally sometime mid cycle I bleed and that never used to happen to me. I bled on the 6th and it looked like thick cm mixed with old (brown) blood, it continued on for the next day . Now it started up again like this except it's red. Has anyone else experienced this?

I have been very stressed out the past month because of finals, 8 month sleep regression, teething, climbing and crawling all over the past month 😚😂

I don't believe I am pregnant but anything is possible I guess 😂 with my dd I spotted once faint pink 6 days after I got pregnant but nothing like this. Maybe just an odd cycle from stress? I don't know if I should count this as a cycle 🙄😝
