If you just had a baby 5 months ago and have an IUD, your body is likely regulating itself to it's new norm. Implantation bleeding is rare. It gets thrown around this app like it's the norm ... I wouldn't stress right now. Take a test a d you'll know

Sounds like implantation bleeding. If it doesn't get darker and is just light pink and then stops after 2 days of that happening, then your prego

I've never had a regular period. And I have an IUD. I've had, and currently have light blood only when I wipe so I'm thinking maybe that's my period? Very light and none on my underwear

How late and has this ever happened before?
