Um help?...

Me(15) and my boyfriend (18) have been dating for almost 3 years. Me and him would love kids but we both want to wait until im at least almost 18. Me and him have been having sex and we plan the days we have sex. I can't get on birth control and im allergic to condoms. I have a big fear of getting pregnant right now because of my mom. He wants to do it more because he has to move soon. I don't know what to do
