April 1st FB announcement

Our next OB apt is the 1st. I'll be 16weeks and was going to announce on FB after my appointment. I didn't even think of April fools day until I seen posts about fake pregnancy announcements that day. I personally think it would be funny to announce that day cuz it's not a joke. All my close family will already know cuz I will call or txt them b4 the post cuz I hate finding stuff out on FB so I make sure close family doesn't. Should I anounce that day or wait?
