Just need comfort

I am 18 and have been with my man for almost a year now, Most of my friends and girls I went to school with are new moms or pregnant. Although I am not TTC i have reason to believe that I am not able to get pregnant. My boyfriend and I do not use any form of pregnancy prevention and I have not gotten pregnant. It's odd to me because I am still young and shouldn't be having fertility issues right now but it does worry me for the future. In a way I guess I am envious that all these people I have spent my life with are now having babies and I'm the one left out. To some this will sound really stupid but I am just looking for some comfort and support. ❤️Savannah
