10 weeks pregnant with twins at 38

Just found out that I'm pregnant with twins. My husband and I are in total shock because this was supposed to be our last baby, #4, now it's #4 and #5. I'm a little worried about judgement from family but don't really care because we both have successful careers, recently purchased a house, and have been thriving where we recently moved to live. I just don't want to hear anyone say did you need more kids or wow don't you think that's a lot. My kids are 3, 5, 7 and my husband and I have been together for 20+ years. This is also a geriatric pregnancy because I'm 38, We've been calling it a a jurassic pregnancy because it makes me laugh hysterically.
