Hi... For the past couple days I've noticed a slight pink/brown discharge in my underwear.. The other day I had a slight pain like a period pain.. Today I noticed a little dark lump in the discharge too.. My period started on the 11th January and ended around the 16th.. I'm just a bit concerned?? I haven't had sex since last March and I have been a bit stressed recently.. Just concerned at the cause so please help ASAP!! Thanks.
