I'm on depo shot & I haven't been on it for a year yet. I just started it a month ago, and you know how they say it will take 3 weeks for it to actually start working? and for you to use a condom? Well, I didn't use one and we had unprotected sex right after I got the depo shot. I've been having alot of pregnancy symptoms: I would feel the urge to throw up (but i never actually throw up) i've been pooping and peeing ALOT! &' i've been feeling pressure on my stomach and sides, even up to my ribb cages alot too. I don't know what it could be. Could I possibly be pregnant? Thank you for your time (:
