1st poem questions

[KLK7]

I wrote a poem for the first time in my life last night. It just popped into my brain. It still needs some work but I think it is worthy of publication in a magazine like Mothering.
How do I know for sure if it is any good?
Where and how do I submit it for publication?
Any other tips for me?

mothering's submission guidelines are found on the website main page I think. It's on the website.

A kind soul here at MDC directed me to duotrope.com. It's a great site.
