Im am 27 years old. I started my period April 21st and it stoped April 30th. I started to have a light period on May 9th and the color was red and brown. Still bleeding the same amount and same color. Not haveing very many cramps and there not as painfull like I would with my normal period. The cramps only last for about 10 seconds at a time and they come and go. Im not due for my period till May 21st. I have never bleed in between periods. Had sex around the first week of May. Do not use condoms and not on birth control. Been with my boyfriend for a year and hes hopeing for me to get pregnant. What could this be?? THANK YOU!!!
