So sorry for your loss, im pretty much in the same boat trying to conceive since august. Ive had 2 miscarriages before 6 weeks, I just keep checking my ovulation and periods and going from there.
One thing for you both is, if you've been able to get pregnant once then i dont believe there is anything wrong with your husband and cannot be deemed infertile.
On the other hand, ive found when you have been trying for a while, you tend to stress about not getting pregnant (because same.. i stress when i think im pregnant, take a test and it comes up negative, its heart wrenching!)
Just enjoy having sex, dont make it a chore if that makes sense. Dont have sex just to get pregnant, enjoy each others company, it will happen. If its happened once, it will happen again.
Im 26 and hes 32, age doesnt matter really when your trying for a baby. (Doctors will tell you different they do say when a women hits her 30's her egg production starts to decline.. but you get women at 40+ getting pregnant easily).
Just enjoy it, dont stress too much it will happen at the right time x
