Thanks everyone, I plan to talk to him about it soon. This gives me more comfort.

Welcome to the forums, @newlywed!  Congratulations on your marriage!
First, I'm going to refer you to a post I made in another thread:
Next, I'm going to point out that in my experience, you will have the most success getting clear guidance if you study out the issue, make a decision (that doesn't mean the decision has to be what logic or math tells you, it just has to mean that you've considered everything you can think of to consider, and then made a decision), and then ask the Lord whether the decision is right.  (This seems to work better than asking the Lord to tell you what to do.)
Finally, you of course need to counsel together with your husband about this.  Find the right time, when he's not stressed or rushing to do something or too exhausted to think straight.   Let him know about these feelings you've had, your doubts about them, and that you'd like to consider the issue with open minds.
God is a God of miracles, and I think that's what my dad's story shows.  But He also expects us to work and think and make wise choices, so there's always a balance.  In your case, you need to consider everything, plan what you can, trust in the Lord, and be open to his reply to your prayer.
I wish you and your husband a long and happy life together with a beautiful family.   I hope you'll stick around and tell us how it goes.
Next you'll get replies which are perhaps wiser than mine (though I consider my dad's story to be wise counsel), and certainly more experienced (since I have no children, so I haven't been in a similar situation).

Revelation for couples should be received as a couple.  That's not to say it can't come to one spouse first, but that the other spouse should also receive it too.

There is this thing called the law of witnesses.  When a revelation is from God, it will not come to just one individual, it will be confirmed by a another person with a stake in the matter receiving the same revelation. 
So please do bring it up with your husband.  He may be having similar feelings, or if he gives it some thought and prayer he may get a confirmation and then the two of you can move forward united in faith.  Or he may receive a different prompting and you can have some comfort that you are not violating God's will in waiting a bit as you plan.  Just say 'Honey, I need to tell you something I've been feeling and get your thoughts on it...'  you aren't dictating to him what will happen, you are trying to work something out together.
I proposed to my wife 6 weeks after I got back from my mission, we were married 6 months later.  I was in school full time and she had a job at a retail store so we didn't have a lot of money.  We didn't wait however, she was pregnant a month after the wedding and over the next 10 years our first 5 kids were born.  Yes there were financial challenges and sacrifices, but we kept paying tithing and it worked out.  We did have to have a friend babysit for a couple years while she was at work and I was at class, but after I graduated she was able to be a full time mom up.  Our kids are older now so recently she was able to finish her degree.  She has a career and I do too and I can work from home so even though our youngest in in high school he still has a parent at home.  My wife says it is better to chase kids when in your 20s and do home work in your 40s than the other way around.
Now that might not be the right path for you guys, but just because you are young poor newlyweds doesn't mean starting a family is impossible or wrong.  You both need to take this to God and then act in faith on the answer.  It doesn't matter if it doesn't seem logical, if you feel peace and confidence from the spirit over it, go with it and trust God to clear the path before you.
