Melatonin - Bred Heifer

[UncleLA]

I have a heifer that is about 3 months bred. She is still a little "spunky" and we are planning to show her in a few weeks.
We've used melatonin in her ration before she was bred; however, I just want to make sure that it won't hurt her pregnacy if we use it again.
Any thoughts?
Thanks.

read on the back of the bottle and see if it says " do not take if you are pregant" i dont think it does but i dont have a bottle with me its all in the show box
