Wanting to be pregnant

Me and my boyfriend have unprotected sex all the time, I'm not on birth control we use the pullout method, and I just want to be pregnant I'm 19 and i know that's young but I want to be so bad and I get disappointed when I get my period. 😔 so I'm hoping maybe I will miss my period for this month. Is that selfish of me? My boyfriend doesn't want kids now but he doesn't try to prevent it. We've been together for 3 years
