I have no experience either, I would be very upset too if it was my DD. But I was myself at that age and my parents were amazing which I will always be grateful for. They never pressured me either way, never lectured me, just supported me. Even though my Mum later admitted they were terrified and thought they would end up raising the baby. My bf parents were the opposite and tried to force me to abort. No matter how hard it is you are doing the right thing being supportive. It's not ideal but it isn't the end of the world and can still have a brilliant life and do well.
