Is Melatonin safe?

To take while pregnant? I will ask my doctor before I do anything, I was just wondering what you guys know.

yeah. I took it. I feel its safer than other sleep meds.

I have read that it isn't. In small dosages every once in a while, I'm sure it's fine. Every day, no.

Tylenol PM and Benadryl are completely safe.

Thanks! I forgot about Benadryl.
