I want to get pregnant at 16

Okay so let me start of with, I’m not stupid, I know I’m young and it’s difficult, I have been pregnant 3 times before but miscarried every time, I still keep the positive tests in my draw, me and my boyfriend have been together for 2 years, but he is the one. You guys might think it’s crazy or every teenage girl says that but I’ve loved other people and I’m very spiritual, I feel him, he is who I was made for, he was made for me. We have never had protected sex, I was on birth control for a year when we met but I came of it as it was making me feel crazy and I didn’t feel like myself, we really want a baby, we are stable, and know how to take care of kids, he has 4 sisters, 3 of them are young. 9 year old, 6 year old and a 1 year old, so he has experience looking after little ones, I have spent the last year looking into pregnancy and conception like I’m someone who can’t conceive, I have sobbed over not being pregnant and seeing everyone around me have babies, my man’s older sister had a baby boy in July, one of my friends accidentally got pregnant and is having a baby boy in February 2025, I feel like it’s happening to everyone that doesn’t want it, and while I’m here praying for it and changing my lifestyle to be healthier for my baby it won’t happen, I don’t know what to do, but I feel like it is also important that I mention my boyfriend had cancer right when he went through puberty so he might be infertile, his doctors are saying they are 99% sure he’s infertile and I feel so cheated, it’s not his fault but of course, me, wanting a baby and would give up anything for a baby, ends up dating a man who is infertile, the doctors are saying we would have to try ivf in the future and all I want is to do it naturally and think “oh am I pregnant?“ take a test and bam I am, idk what to do anymore guys, if you want more information on the situation with my boyfriends cancer and stuff I made another post about it, click on my profile it should be there
