Do you thin I'm pregnant or am I okay?

I was having sex with my boyfriend and we were using a condom. We only did it for about 20-30 Seconds and then I said stop now and he pulled out very quickly. I looked at the condom and it had slipped just a little bit, not a lot. There were no holes in the condom and he didn't cum. I'm worried that I could be pregnant from the condom slipping a little like it did. Like I said it didn't slip like half way down or anything and he didn't cum as there were no holes. Do you thin I'm pregnant or am I okay??? Please help please
