Scared

I lost my virginity today with my boyfriend. We used a condom, it didn’t break. We did it for a while, and had to keep reinserting his penis. The condom didn’t fit quite right, and I am in my fertile window. I am not ready to have kids and i want to know how likely it is that I pregnant, and where I can get a pill to counter this if I am, and just to be safe. Ps, he said that he came but didn’t know until he took the condom off. Also, we did it for a long time. Please please help. Also, I’m not looking for any negative comments, I did research, I used a condom, we were both ready. I am simply looking for answers as to how likely it is that I’m pregnant, and a pill I can take to make sure I’m not.
