6.5 weeks-brown spotting

Krista
Had some brown spotting this morning-just when I wipe-I take progesterone so
I wear a panty liner at night and there was nothing on it--but just when I wiped there was some brown on the toilet paper. I did have some cramping last night before I went to bed, but I had horrible has all day yesterday and it felt more related to that. Has anyone else experienced this? I think I should call my doctor even though it's a Sunday.
