Announcement with same sex parents

So me and my wife did at home insemination with donor sperm and got pregnant the first try (honestly didn’t think it’d be that easy) well I am doing good and everything our family knows and I got a ton of “how” “what did you do” “did you cheat on your wife” and I’m extremely nervous to publicly announce.... should I just get over it? I’m not going to answer those questions for anyone but if they are to ask what do I say? .....

UPDATE: I kept getting comments like this one

So I made this

I also had people messaging who I don’t really talk to asking how as then not congratulating. But it’s okay I also got a TON of positives and I still am more then excited to meet our little baby
