Super excited

Am

Found out 3 days ago I’m pregnant, around 5.5 weeks, I’ve been wanting to tell my 5 year old daughter so bad she been bugging for a while for a little sibling and so happy she’s going to get one but wondering if I should still wait until 3 months?, so should be due roughly December 2 and I had my daughter dec 27 2013 🙄 might have two kids both with birthdays in December
