what is going on with me?

Selma
Okay so my boyfriend and I have been dating for a year and a half. I'm graduating high school next Sunday but my boyfriend is a junior in high school.  
So normally I tell my boyfriend to pull out just for added protection when we have sex but I am on birth control and we use condoms every time we have sex. But lately I've really been wanting him not to pull out. I have no idea why. But I've really been wanting a baby. And I talked to him about what I've been feeling and wanting a baby. But I don't want to add pressure or stress or anything by us having a baby. But I for some reason really want one. 
I'm thinking maybe it's cause I had a miscarriage two years ago with an ex, and some of my friends have gotten pregnant and have a kid and I'm like lowkey jealous because I never got to have what they do. But I truly have no idea. Someone help me understand what's going on😪
