I would like to know if I can take chamomile, valerian, and melatonin during the first trimester.

It is generally not recommended to take chamomile, valerian, or melatonin during the first trimester of pregnancy. It is important to consult with healthcare professionals for guidance on managing symptoms during pregnancy, such as nausea and insomnia. There are non-pharmacological strategies that can help improve sleep quality, such as maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and avoiding stimulants. It may take some time for these strategies to take effect, so patience and consistency are key.
