I am experiencing some heavy brown ordorless discharge, it has been happening the past week or so and comes and goes. Ocassionally it is barely noticeable in other Ocassions it come out in large amounts. I have had sex without using condoms. However I am on the pill and have not missed a pill so far, I do not have a period with this pill therefore I cannot tell if this is breakthrough blood or not. I have only started to get concerned as it seems to be getting heavier. I have had some itchiness but no burning and also some slight bleeding, please advise me on what to do next, I'm worried in case I'm just being a hypochondriac.
