I just found this on my undies.. I started my period today. Should I be worried?

Question

Answer

No, that's normal. It's uterine lining. 
Sometimes you have it more frequently. There's a chemical that gets released in your body on your period that's there to help break uterine lining up. 
Sometimes you release less of that chemical for minuscule reasons. Normal and not something to worry about.
