Hi, i was supposed to take my 3rd shot of depo provera, but had to cancel and will be taking it tomorrow. Ive gotten the shot every 13 weeks (the 7th of every 4th month). Since I'll be a day late for the shot, what are the risks? Would it be like im taking it for the first time, where ill bleed for months and gain weight, and what will be my chances of getting pregnant with unprotected sex ?
