A Baby... Please?

How good it is to have a place like this, where you can ask so many sisters for advice! Masha'Allah. I hope you're all doing well.

The situation:

My husband has a daughter (9) from a previous relationship. I wasn't clever enough to talk about our future together and if he would like to have any more kids, when I got married to my husband at the age of 22. At that time I had no need to have children of my own and I even though it would be enough for me with just his daughter. When I turned 25 things changed and I suddenly felt a deep desire to have my own children some day (not in too many years) and now at the age of 26 the desire is still there and I almost can't imagine how my life would be, when I get older, and I hadn't gotten any children of my own!...

In the beginning of our marriage my husband always said, that you can't, as a man, marry a young woman and say you don't want to have any kids (if she hasn't gotten any already). I agreed with that... And still do! But lately he's said things like "do we really need to have children?!" (he thinks it's sooo much work!)... And it makes me quite uncomfortable, 'cause I really don't want to be the kind of woman who forces her man to have kids with her :-/ and I also know that my husband has a hard time with women who want to have kids no matter if the husband likes it or not!! 

Do you have any advice for me and has somebody perhaps been in the same situation?

I really find it hard to pick up the subject with my husband 'cause I am afraid of what it will lead to... Afraid that he will ask me to choose between him - or to leave and have kids with somebody else some day...

Of course I make duaa too!... And I also know I should just trust Allah (swt) and not worry too much...
I really would love to experience being pregnant and experience the unique love (as they say) that you experience with your own baby/kids... I would feel as if I would not be completed as a woman, if I didn't have kids and I feel like I'm already in love with that little baby who isn't even a reality yet......
