Pregnancy... Miscarriage...Ectopic??? HELP

Holly
Need advice..... I was 5 days late with 1 negative pregnancy test and 2 with very faint lines. I've never been late...
A week prior to my expected period I had severe cramping off and on for 4 days. My breasts then became massive and i had cream colored CM. Then Monday it was brown with spotting. I have had medium bleeding for two days now. My left and right sides have pain sometimes, but nothing severe. My breasts are back to normal, but I'm still a ragging B! I have been trying to get into a doctor in the new state a live in, but no luck getting in asap. Would you go to the ER if you were me? Thinking about taking another test...
