I been testing my ovulation since August 18th my last period ended on August 1st...from August 18th to August 31st i have gotten negative opks on September 1st i got my first positive opk then September 2nd it was negative then September 3rd i got a darker test line on my opk so i thought ok maybe i got my first positive opk on September 1st n 36hours I ovulated cuz i had a even darker test line on my opk so i was told to stop testing after ur 1st positive opk which i did but i saw other ladies using their opks as pregnancy test n i wanted to try it out so i took a opk and it’s positive then around 2pm today i got brown discharge so am i still ovulating?are my hormones high? Could i be pregnant or what ? ...i took a pregnancy today but can anybody explain this
