TMI! help brown clot- 5 weeks pregnant

Courtney
Hi all, 
I was wondering if anyone else has had or is having the same issue. 
I just found out I was pregnant Saturday and put myself at 5w2d today! 
Since I found out I've been doing good, leafy greens, proteins, no caffeine, no alcohol, prenatal vitamins and scheduled an appointment with my OBGYN but that isn't until Dec. 5. 
Yesterday I started getting a brown "tinge" when I wiped but only when I wiped no spotting through the day. Today starting this morning it was the same thing except now it is also sporting a little bit in between. I just went to the bathroom and had a nickle sized dark brown clot. And light cramping today very, very light and it all day just here and there. 
But I am freaking out!!!!! 
Anyone have any insight to this??
