If the condom was completely empty, it sounds like to me that he took it off without you knowing. Also if he is older than you it is possible what he did was statutory rape.

If he did indeed take off the condom after you both agreed to using one, you can press charges for this as well.

On the pregnancy, there is a high chance you are pregnant. I say wait until your period is actually due to panic,but if you're really worrying, get a blood test at the doctor's.
