Frequently Asked Questions
Is melatonin safe during pregnancy?
There isn't enough research to confirm melatonin's safety during pregnancy. Most doctors recommend non-supplement approaches first. Always consult your provider before taking any sleep aid.
Is it safe to sleep on my back?
After 20 weeks, avoid sleeping flat on your back for extended periods — it can compress a major blood vessel. If you wake up on your back, don't worry, just roll to your side.
Will pregnancy insomnia affect my baby?
Mild insomnia won't harm your baby. However, chronic sleep deprivation is linked to longer labors and higher C-section rates, so addressing it is important for your wellbeing.
