Two weeks ago I had my period and was havn sexual intercourse during it and into the fourth week..i went loo and a huge browny gooey slimy discharge with red small blood in it came out as I wiped and still more was coming out and this is my first time getting this , usually my discharge is clear and my lower stomach part is crampy,, headaches feel like the vacuum suking my brains out, mouth taste like metal something What is this?
