I am two days late for my period (and I am always very regular) but since day 21 of my cycle I have been having brown discharge every day (usually when I wipe but sometimes almost small stringy clots). I took a pregnancy test back on day 24, which came out negative, but I think it may have been too early to tell. My husband and I are trying to pregnant but I am thoroughly confused as to what is going on. Has anyone experiened anything similar?
