Tmi no pics


I've had like spotting with mucus on the Thursday then went and came back on the Friday about two hours after sex it was a pinkish colour still with mucus then it's carried on from there but late Friday night I checked and now it's a brownish bright red colour not alot at all still with mucus my period is actually due next Sunday and this seems so strange to me I've put tampons up there and all mucusy but this morning I've experienced pain like the dull period achy but I normally am very heavy by now and not mucusy at all I don't get my body whatsoever please someone help and tell me what this might be thanks.
