clonazopam during pregnancy

i am 16 wks today and for the last 4 nights i have been having restless legs on top of that ive been feeling depressed and having severe anxiety. im not taking anything for it but just wondering if i take a 0.5mg of clonazopam for the nite until i can get to the doctors in the morning will my baby be ok? my previous pregnancy i was on life support for almost 2 months and was givin morphine twice daily and it had no effects on my child. he was a healthy baby boy 8lbs 11oz 23in now hes 8 and still happy healthy baby boy. i read online its ok to take during 2nd trimester but im still worried.
