Common questions about Second Trimester Pregnancy Milestones Calculator
When is the 20-week anatomy scan scheduled?
The anatomy scan (level 2 ultrasound) is scheduled between weeks 18-22, with week 20 being most common. It checks all major organ systems, measures growth, and can often determine the baby's sex. Hospitals schedule it as a specific appointment - ask your OB at the 12-week visit.
What is "quickening" and when does it happen?
Quickening is when you first feel the baby move. First-time mothers typically feel it between weeks 18-22. Second-time mothers may feel it as early as week 16 because they recognize the sensation. It feels like flutters, bubbles, or gentle taps initially.
Can I travel during the second trimester?
The second trimester (weeks 14-27) is generally considered the safest time to travel. Morning sickness has usually passed and the third trimester discomforts have not yet begun. Most airlines allow travel until 36 weeks for single pregnancies. Always check with your OB before flying.
