I recently got off of the depo shot, ( Oct-15 was when my last injection was due ) & i have had pregnancy symptoms. I looked in my calendar to see when the last time I bleed was; And my period ended on Nov, 10.. Witch means I would have ovulated from Nov,13 - Nov,19. Witch is were I would have conceved.. On Nov, 24 I spotted Pink, & it only lasted for no more than an hour, We looked it up, and they said that is Implantation bleeding and I haven t had a period since.. We looked up all my symptoms and they all happend in the order and the week they were supposed to. I took a pregnancy test and It came back negative, I plan to retake on in the morning.. Could I be pregnant ?
