I've done some reading on taking melatonin while pregnant, and most of it is contradicting both sides have good points, and make sense whether it's safe to take during pregnancy or not. I've never taken it, even though I've had sleep problems all my life, and during pregnancy sleeping is even more difficult for me. My question is: have any of you ladies taken melatonin while pregnancy, and if so did it help? Did I cause any problems?
