Worries about age when ttc?

Hi everyone! I'm 30 and my partner is 44. We've been together for 6-1/2 years, neither of us has children. We recently decided to ttc and last october we were blessed with our bfp! We were so excited, but sadly, we started miscarrying on Dec 1st at 10 weeks. We definitely want to try again, but i was wondering... Should i worry about the daddy's age? How old is too old to conceive?
