I woke up today and was happy to see that my bed sheets did not have blood on them, neither did my pants. However, I felt something dripping down there, so I rushed to the bathroom. My undies had blood on them. When I took out my Lunette size 2, I saw that most of the blood was inside the cup (it was only 1/4 or less full though), but there was one big glob of blood on the outside of the cup, which was where the blood drips come from, i think. How come my cup caught blood, but did not catch that one big blood glob? What can I do to fix that?
