I got my depo shot than the three months went by and it ended august 3rd.. the way my periods fall I was supposed to be in high fertility from august 4th to the 8th and ovulate the 9th... I've been having pregnancy symptoms but got my period the 23rd stilll having symptoms. I was wondering if it was possible I still had high fertility and ovulated that close to coming off the depo considering i had only the one shot and wasnt on it but only the 3 months
