Pregnant on last week of depo shot?

“I got my first depo shot on November 4,2005 and I’m due for next Shot on Feb 4 ,2006. IS there any chances that I can get pregnant on the last week of the shot? I also have not had my period this month and have been gaining some weight is that normal.. And the last 3 days or so I have been cramping is that normal?”

A: The shot is 99.7% effective, so there is always a slim chance someone can get pregnant at any time, not just the last week. Your chances of getting pregnant do not increase right before your shot is due. You are protected until Feb 4th. It is normal to not have a period and to gain weight while on the shot. If you are concerned, I urge you to contact your physician who gave you the shot.
