Your call, mama! If you want to shout it from the rooftops or post on Instagram as soon as you get a positive sign, go for it! (Hey, at least you won’t have to fake drinking wine.) Just know that the risk of miscarriage or complications is highest in the first trimester. That’s also when you’ll be undergoing some pretty important testing and scans to make sure the baby’s doing well. For that reason, many mamas choose to wait until week 12 when they find out their little babe is thriving. Some women wait even longer, especially if they have to undergo more rigorous testing like an amnio at around 16 weeks. Just know that it’s entirely your decision, so do what feels right.
