My parents are not religious, but my Mum would have been very disappointed with me, and surprised if I’d found myself in this situation.
My Dad would’ve got used to the idea quickly, but my Mum would’ve kept on saying that I was doing things ‘in the wrong order.’ My Nan also isn’t religious, but would’ve been disgusted with me, and would’ve been telling me to quickly get married in a registry office before I looked pregnant. I have heard her tell others to do this before, so I know that’s what I’d have been told!
Also, some people of different cultures would be very disappointed in their children for getting pregnant/getting someone pregnant outside of marriage, regardless of their age. My DH was raised into a different culture and religion to me, and his parents would’ve been completely mortified if I’d got pregnant before marriage (even whilst engaged), as sex before marriage is seen as a sin. If this had been the case, and anyone in their community found out, it would’ve brought ‘shame’ on the whole family, and people would’ve avoided, and even shunned them.
I knew someone from a different culture to me who became pregnant whilst engaged, and was told by her parents that she’d have to get married in the next month. She was also told not to even tell her in laws to be, as they’d think she was ‘easy.’ Never mind the fact that their son would’ve been the one who got her pregnant!
