So I am 18 and I got the depo Shot about almost two weeks ago and I haven't started my period yet, my boyfriend did finish in me about two days when I got the shot but I took a plan B and well we had sex today and the condom ripped when he finished so I had to take another plan b. but I've been hungry latley and I have been urinating a lot and getting random cramps in my lower stomach. Could I be pregnant? Please help. This is my first time on the shot.
