help please I can't see a doctor

Y`Marrea • married to love of my life 💍 mommy of 2 boys🩵 and 1 girl🦄

I don't have insurance right now so I can't go to the doctor. for the past 3 days or so I've had light bleeding when I wipe. I don't use a pad or tampon because it's just when I wipe. it started off bright red and now it's like a pinkish red. as the day progresses it always gets lighter and then stops. I'm not sure if it'll happen again tomorrow and my cycle is super irregular. any idea what it might be?
