Is spotting for a month normal?

Sarah • Mom. Wife. Doula. Currently have one 2 year old daughter. Planning on trying for #2 June 2018.
I have been spotting since the day I found out I was pregnant. A month has passed and I take a pregnancy test every few days and it's still
Positive but the very light spotting continues. I don't have cramping.  The color is always different. Red, pink, brown. My doctors nurse said "oh that could be an atopic pregnancy, miscarriage, or that everything is fine. If you aren't having any pain just wait for your appointment in 3 weeks." But I can't stop worrying. If my doctor won't see me should I go to the ER or chill out?
