Father asked me not to get pregnant

So I am 5w2d. I'm engaged, 33 years old, planned pregnancy, living in our home together (bought a house together), financially secure. I was talking to my dad today and he said something has been bothering him for a while. He asked me not to get pregnant till at least the wedding. (It's next October because of schedules and making sure we pay everything upfront rather than go into debt over a party). Told him it wasn't fair that he ask that of me. His reason was because it's not right to have a baby out of wedlock (he was pretty good with us living together) and that he doesn't want something to happen and I be left alone. Keep in mind, he actually likes my fiancé so it's not that. It just hurt so badly. I came close to saying "by the way... I'm actually pregnant".
