Okay so I got my first depo provera birth control shot 12 weeks & 4 days ago in counting The clinic said the last day for me to go in before it's late is Oct 7 2015 I have a question I there a possibility I could be pregnant because the 3 months ( 12 weeks ) is up? & I'm also trying to concieve do you think it would be easier if I missed the shot & had unprotected sex since it was barely my first shot? what's the chances of me getting pregnant soon if I skip this shot.
