Help...I have been spotting for a few days, although not a huge quantity it is becoming progressively darker brown and more sluggy ( sorry but don't know how else to say it). I have read everywhere here about other peoples experiences, but when should I start to worry (more than I am now) and call doctor. You are all the only people I know to turn to. I have had a few minor cramps - and just put those down to stretching etc. Am I just being paranoid or is this the first stage of m/c. Am at work in stupid open plan office so ability to talk to doctor is limited.
