and it was bright red blood and a lot of mucos. My period was`nt due till the following wed 26th, so i thought i`d done some damage as i`d just played a tennis match ! But no more bleeding followed, just a little brown discharge on wipeing for 2 days.I`d never really known about implantation bleeds until now! Then on wed 26th i did`nt start my period, nor have i had any bleeding since, but i`ve had period pains everyday, in various levels of discomfort ever since? I`ve also had some mild indegestion & nausea, and my food tastes metallic? I`m full of energy one minute and could crawl into bed the next, especially when this dizziness and faintness comes over me!And i`m fed up of these dull frontal headaches everyday. Three urine tests i`ve done have been negative, and 3 days after my sept26th period was due i begged the Dr to do a blood test which came back negative aswell ! But i am convinced that i am Pregnant or have a serious illness with all these strange symptoms? Any Answers anyone, Please ????
