Calf pain and spotting?

I'm 7 1/2 weeks pregnant. Been spotting on and off for two weeks (brown) last night I had light pink and this evening calf pain, like it was blocked or something. History of mc. This is the furthest I've got so no idea if it's standard. Also a little crampy but I do have a cyst so o don't know if that effects. Similar stories or comments welcome.
