If I had sex on March 20th and my period comes the 25th through the beginning of the next month anytime in between there and I take the depo shot & he had a condom on....what are the chances of me being pregnant?? I am having the symptoms  of my period coming like gas , a bit of acne , and moody. but it hasn't come yet....Should I be worried that I'm pregnant? I'm only 16 I'm not ready for a baby!!!!
