Possible miscarriage?

For a couple of days i've been lightly spotting pink & also some bright red, but not a lot. Twice when using the bathroom a small string of blood came out of me (similar to when we're on our periods). I haven't been able to see my doctor. I'm supposed to be 7 weeks right now. The other day i also had very light cramping similar to period cramps. My morning sickness (all day nausea) went away last week. Since i can't be seen by my obgyn, should i go to a hospital or is an urgent care okay too?

(Asking because hospitals have long wait times & expensive bills!)
