Please take a minute out of your time to help me ease my mind!?

Why on earth joking around you put *** inside you? Thats REALLY odd. To answer your question it is very likely you could have became pregnant from even the pre-***. It still contains sperm and if you were ovulating around that time the sperm can live in your body for up to 7 days. So, my thoughts are that you could be experiencing implantation cramping or your ovulating later than you think and your just now ovulating and sometimes that can cause cramping. The only thing you can do it wait and see if you miss your period or not.
