Having more children after our first...

If you had a hard pregnancy with your firstborn and your husband knew this and still wanted to try for baby #2... Would you get pregnant again for the sake of your child's life and husbands expectations?  
It's really important to my hubby that his child has siblings as he has a big family... What are your opinions? 
Opinions on having only one child or more? Don't want to disappoint my husband as he is really particular about this issue... 
Any advice appreciated. 
Thanks in advance!
