Can you have pregnancy symptoms while on depo? i had unprotected sex before i got my first shot. now i think i'm pregnant. is that normal?

What depo: First of all, what Depo-Provera (medroxyprogesterone) are you on? If you are mentioning depoprovera, here is my guess: menstruation/ menstrual bleeding/ bleeding irregularity caused by Provera (medroxyprogesterone) might make you feel you are pregnant and it is hard to differentiate. But there is still a chance you might get pregnant before putting on depoprovera. In this case the latter will cause birth defects so you have to consult ob/gyn.
