About 8 weeks pink blood on tp

Dee • My rainbow baby is due in Aug 2015 <3
So I haven't had any bleeding really expect once a few days ago that was brownish.
This morning when I woke up there was pinkish blood when I wiped and the tint of the water was red. 
Just went to the bathroom again and when I wiped it was pink again. It's almost watery. Should I be conserned?
