Honestly, my oldest child is 22, and I haven't yet so...

Never. There is always something to worry about. First it’s making it to 10 weeks/first ultrasound, then it’s making it to the 2nd trimester, then it’s making it to the 18/20 week anatomy scan, then it’s making it to 24 weeks (when baby can live outside the womb), then it’s making it to full term etc. and after birth is when the real worrying starts 😂😂😂
