Pregnancy ๐Ÿ˜…๐Ÿ˜…

My bf and I have been together for 4.5 months, I know it's not very long and we are only young (18) and we started having sex at only 1.5 months. The sex is always mind blowing and I love him so much ๐Ÿ˜ Side note: we don't use any sort of protection just the pull out methodย 
Is it weird that I want a baby? Like everytime we do it I almost want to say to him to cum inside me ๐Ÿ˜…๐Ÿ˜Š
Please help!!!!
