so, I got my first depo shot on november 12, I started my period in november on the 6th, my ovulation day for that month was the 22nd. I haven’t had a period or any bleeding ever while on my depo unless it was about a week until my next shot. I had sex on the 21st of december (would’ve been ovulation day for december) and he didn’t pull out. yesterday I had some spotting and have been having pregnancy symptoms for a few weeks. could i be pregnant or could I just be getting sick?
