Weird “spotting” at 18 weeks

So when I went to the bathroom this a.m., there were very small flecks of blood in the discharge. No sex; no pelvic exam; no exercise. I have a little cramping now and had spotting at 13 weeks with an irritated cervix from an unknown yeast infection. At that time my OB told me not to scrutinize over any little spotting. The ER seems extreme. Thoughts? Of course it’s the weekend.
