Boyfriend wants kids

We were bowling the other night with family on thanksgiving night and mg boyfriend out if no where says he wants a kid so bad, ever since then it's been on my mind, he did cum in me while I was fertile knowing I'm not on BC. So I think I kinda want a baby too but I chose not to be on BC because I was having too many side effects. I would feel like a failure if I actually got pregnant. I have one more year at Ohio State. I just wanna finish school and then get married n then have kids. He is 30 and I'm 24. We have been together for 2 n half years. We plan on getting married but right now he's in pharmacy school. We love each other though
