my period this month was normal flow on the 3ed and 4th but the 5th blood was very minimul and brownand the 6th which is today there is no bleeding just a hint of a tanish color after urinating this morning. now i have cramps but not the normal feeling of period cramps there is no bleeding and the cramps are sharper then my normal period cramps. could ovulation or implatation have happened during my period or could what i thought was my period be implantation bleeding even if the bleeding looked normal the first 2 days???????
