Frustrated

MV
So I have been having brown discharge/spotting for 7 days now and its not a lot but I am starting to get concernes because its been a while. I called my dr office and the nurse keeps telling me its ok as long as its not red blood and no foul odor. She told me its too early to bring me in and they dont wanna cause unnecessary panic ( i am 7 weeks today). They seem to be ok w it but I cant gelp but think the worst :( my first allt is june 21 so I still have a while to go! Anyone experience anything similar?
