Unprotected sex

My boyfriend and I did the deed. He finally took my virginity. And we did it raw so no condom or protection.

I figured we would be okay and he did pull out. However I am ovulating (as per glow!) And my chance of pregnancy is like 31% the highest percentage!

Should I be worried.

Also to I'm 19 he is 27. I wouldn't say we are ready for kids. And not from a financial perspective. We both make good money. But I don't think we are mentally prepared for a baby just yet. We talked about it and said maybe in a few years but not like next year you know.
