Fast forward the next two days and no period, I took another test... Still negative. Then 2 days after missed period I went to the bathroom and saw a drip or two of bright red blood, immediately I put a tampon in thinking I started my period. When I took out the tampon that night there was no sign of menstration, now it's been a day and a half with only a few drops of blood in the toilet. Naturally I googled it and all I'm seeing is  implantation bleeding. It seems to align with what is going on with me but they say spotting should be pink or brown but my blood was bright red! Has this happened to anyone???
