I am 7 weeks pregnant. I am suffering from insomnia and it is getting worse now. I used to take liquid Melatonin where each dropper was 1 mg and I never exceeded 5 mg a night, nor would I take 5 mg all together. I used to take 1 mg and wait for an hour then try again. Since I have been pregnant, I have not tried it. I am only getting 2 hours of sleep at night for the last one week. Can I take the liquid Melatonin during pregnancy? What is the recommended dosage?
