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.
There is nothing to feel ashamed about. Ultimately it boils down to who has financial responsibility for the child, it’s not a moral judgement.
In the end, both you and the child will be better off for having it done.
Removing doubt will defuse so many future arguments. I definitely see how being asked for a paternity test could hurt but it’s a temporary hurt. Uncertainty could cause long-term hurt and damage any chance of relationships developing in a positive way.
