Question

Angel • My Husband and I have been married since Jan 15, 2015. We are pregnant with our 3rd and last baby (2nd together). We have a 3 year old daughter a 16 year old daughter from a pervious relationship and he has a 14 year old daughter from a pervious relations

So I couldn't sleep last night, so I took a 10mg melatonin. I just read that while pregnant you shouldn't take over 3mg? This is the first time will everything be ok? I am 15 weeks 5 days.
