"Can I take something like melatonin or something else for insomnia while pregnant? I am 14 weeks pregnant."

It is not recommended to take melatonin during pregnancy. Instead, try to establish a regular sleep schedule, avoid napping in the afternoon, create a conducive sleep environment in your bedroom, avoid screens before bedtime, avoid stimulating drinks after dinner, and eat a lighter meal in the evening. These tips should help you sleep better without exposing your baby to potentially unsafe medications.
