my period started on february 29 and i had sex with my boyfriend on march 3 which was the 4th day of my period. then on march 9-10 there was this weird feeling (a little pain and discomfort)that i had in the region which might be my right ovary(not sure tho). today which is march 11, i went to the bathroom and noticed clear sticky vaginal discharge with a little brownish color.. is this normal? im 18 years old btw
