Implantation Bleeding

Hi all!

Does anybody have any experience with implantation bleeding on the pill? I don’t always take it super effectively and I was also on amoxicillin for 10 days and didn’t use a form of back up contraception. I think I’m having my period like normal but it is super light pink and it’s been like this since Friday. Usually my periods are heavy and dark red. If anybody has any insight I would appreciate it!
