Discharge/blood

Caitlin • Married 2 years. Rainbow baby boy born 4.27.2021! ❤️

I didn’t take any pictures but AF is 4 days late. Having discharge that is slightly red/pink and a little blood but also egg white type discharge. Not TTC but not preventing with the hubby. Did not have sex during the app’s “fertile window”. Still new to learning what discharge means what. Any advise or wisdom is welcome 😊
