coming off the pill?

Jessica
Hi, just a little confused- I stopped taking the pill (rigevidon) on Thursday (no longer want to be on bc) and I woke up this morning at 4am (Saturday) to a light pink fluid discharge. Throughout this e day today I've had really light bleeding and bad cramps. 
I can't find anything online about bleeding 2 days after stopping the pill? Most of it says 2 weeks. 
Anyone experienced this? Thanks!
