7w3d bleeding/clots ??

Ashley
I am 7 weeks three days and last night when I went to the bathroom I had a decent amount of red- brownish blood in my underwear and a small clot. I do have son cramping but that's been pretty consistent since I found out I was pregnant. This morning when I went to the bathroom there was still some spotting but more of a pink red. 
Is this normal at all or something I should worry about?
My DR is closed till Monday and I just don't want to spend all day at the ER if not necasaary.
