Hello everyone!

I am 4 weeks and 1 day. I tested positive 4 days ago and am very excited. However, I have been spotting the past couple days. It's only noticeable when I wipe it's a brownish pink/orange color usually watery looking. I do not see it every time I wipe. Usually about half the time. My first appt. Isn't until March 9th and it's a brand new doctor office. I do not know if I should be worried and call my doctor or not? Anyone have any advice?
