Okay so I finally had for the first time?

Im 13 years old and yesterday morning I had with my boyfriend Andre. It was amazing and it was the most pleasurable thing I have ever felt. Im about to begin my period and we plan on having for the rest of the week everyday. Oh and we didn't use a condom the first time and were not gonna use one today, we are gonna get some though. He didn't *** inside me at all. What are the chances of me getting pregnant??
