Advice please

My husband and I have been TTC for 2 & 1/2 yrs now with no luck. My first preg (2 tries no protection) ended with miscarriage. Second preg took 6 months to concieve. Delivered a healthy baby.. Now can't seem to become preg. We both want another child but my husband is sceptical of going to a fertility Dr to try and get answers.. Any advice??
