Foster adopt a child? Yes or no?

Kaykay • Marine wife, 3 fur babies, and a whole lot of Love 💕
Weve been having a tough time concieving no luck with it. But not yet , cycle day 57 and still mo period-_-
Weve been married since Dec 2014.
We probably will concieve at one point yes, however in my heart i know i want to adopt a child also. EVERYTHING in me yerns for a child and one to adopt as well. 
Im a stay at home wife and my hubby is in the marine corps in California, US.
We have our home and our dogs. He is 23, and i am 21.
If my Husband agrees to adoption should we ? Yes or no and why?
