So its my period time usually during period red blood comes but this time at the time of period lot of dark brown colour appeared on my pad like pad was almost full and on second day it was less and today is 3rd day and it is same so I am confused that is it normal spotting or something related to pregnancy? I am worried please let me know. And last I had sex 18 days before but I am pretty sure that no ejaculation was there. So let me know that it is normal asap.
