When to tell hubby?

Jessica • Married Mommy to an almost 3 year old girl and another girl due 9/20 💕💗

I know this is obviously a personal decision but when should I tell!? I took an early result test so I’m only 2.5 weeks along. Last time (we have a 2 year old) I took a clear blue at about 3 weeks along and couldn’t not tell him right away I was so excited. Thoughts? When do you tell?
