Trying to Conceive

My husband and I have been trying to have a baby for going on three months now. I honestly thought that this time in our relationship would be fun and exciting like he wouldn’t be able to get enough but honestly I feel like he has no sex drive at all anymore. I wonder if it’s the pressure of trying to get pregnant, pressure at work or something completely different. He has been under a lot of stress at work as well but we try not to bring work in our home life . I’ve always had a very high sex drive our entire relationship so wanting it every day is it new for me. I almost wonder if he thinks I just want him for the good stuff lol but that’s not the case I love the man to death . In the beginning he was the same but lately if I don’t initiate it doesn’t happen. Has anyone had these issues.
