Opinions please

Alright I’ve gotta let it out somewhere I figured I would here me and my man both have baby fever really bad I’m 15 and he’s 17 and we’re honestly thinking about trying we both know our families opinions on the subject but they don’t know that we are gonna try we know they won’t be the happiest at first but then again they wouldn’t be all that mad they would support the both of us through it I just want some opinions about our situation

(Edit): my man has a good paying job my parents have already told me that things aren’t like they used to be that if something happens it happens and they would support me no matter what happens. His family is honestly dying for a grandchild when we were on the phone last night he ask his stepdad what he would do if he got a girl pregnant and he said well I wouldn’t be mad or upset with you because things do happen but the only thing he was really concerned about is me still being in school but where I go to school you can graduate early and all kinds of stuff you can have only 1-2 classes a day for semesters because it would add up for you to have enough credits to meet the requirements for the high school diploma I get that I’m young and everything but in the end our family’s would support us
