Ive been off my depo shot since april. Bled for a few days after. A month later had a full period. Around mother's day weekend. (I can't remember the exact dates) I spotted like a week and a half later very light maybe 2 days. And now based off my last period of mother's day weekend I'm 4 days late.. I have taken pregnancy tests and all have came back negative. I feel like I am pregnant but it's just not showing. How later after your missed period have you got a positive? And how much longer should I wait. Both my other 2 I got positive shortly after my missed period. And I just knew something was different. I still had monthly periods on the depo shot as well. Any suggestions would be appreciated. :)
