I’m 15 weeks and 1 day pregnant today. I’m also young (18), so this wasn’t planned or expected. When my boyfriend’s parents found out, they asked for a paternity test. On my parents’ advice, I agreed to it. Even though I have nothing to hide, it still felt humiliating.
As others have said, it’s a pretty reasonable request by his parents, they need to protect their kid. Doesn’t mean it can’t feel humiliating.
On the positive side, you avoided decades of little remarks (definitely meant as jokes) about how he might not be the father from his parents.
Also, if you ever need to go to court, you already have proof it’s truly his kid.
So, I’m not saying it doesn’t suck and doesn’t feel humiliating, just trying to provide a few positive things to try focusing on.
