Red spotting 5 weeks, help?!

Ok ladies... I'm 5w3d, and I've been experiencing period-like cramps on and off all day. An hour ago, there was light brown blood on the toilet paper. I checked with my finger, and there was a drop of red blood, pretty bright. Nothing since, but I'm still cramping. Any suggestions? I'm really worried.
