Completely agree! My sister was conceived by IVF after 10 years of trying and I came along as a surprise. It's a bit of a family joke that they "bought one and got one free" never made me feel unwanted or anythingTwo of mine were very much surprise babies (how much of a surprise can babies be when you’re having regular, poorly protected sex in your twenties) and I think people should be more open about it. A surprise/unexpected pregnancy doesn’t mean unwanted and her being so prim about it adds to that societal judgement.
This is a great book https://www.amazon.co.uk/Oops-How-Rock-Mother-Surprises/dp/1440562067/
