what is this?!

Abigail
I posted last night about some bleeding I've been having and thinking it was my period. Today it is heavy and still bright red/pink. It's NEVER heavy. It's always light or medium. Some clotting. Is this normal? Here is what I posted last night: I've been bleeding a brownish color/discharge for about a week now. Tonight I felt a gush of blood and it was bright red/pink. Is this normal??? I thought the brownish discharge was my period because it started out spotting then a light brownish color for days and now it's a bright red/pink. This has never happened to me before, and we have been trying for another baby. 
Should I be worried?
