When I was cleaning our toilet and lifted the toilet seat to clean underneath, there were the usual stains and splats but amongst it were undeniable splashes of blood. This is not period blood as my Mirena Coil means I don't have periods. So it's likely it has come from the bowels or bladder of someone in the family. This is worrying but I'm not sure how to approach it with my husband and daughter. What would you do?
