So i got my period on August 10th. It lasted about 5-6 days... i knew i ovulated on the 23rd bc i had extremely sore breast and cramping and ewcm and the it all went away... i am ttc so did it at all the right times plus about every 3 days then on... i was supposed to get my period Sept 8th no pms no period until the 19th and there was maybe two spots of blood it was all brown discharge and it lasted about 35-6 days... now a week later i have EXTREMELY sore nipples like shirt rubbing them hurts bad... i am not too sure what to think.. it shouldnt be ovulation but i did a pregnancy test a week before i got the brown discharge and it was negative... what do you think??
