Need Advice!!

So been TTC for 7 months. Already changed diet, taking supplements, <a href="">tracking ovulation</a>, etc. I truly feel like I'm doing everything on my end. On the other note, I feel my husband is not. When I'm in my most fertile days, we aren't making the most of our time. Then he says, all I care is about sex. Not true. But yes, in order to conceive we have to do that. So sex is on my mind those days more than not.  Anyone else feel this way? What do I say?! I'm just beyond frustrated. It's hard enough as it is to keep track of everything and want something so bad and for it not to happen. Just thought my husband would be more excited to try and more supportive. I feel all alone in this journey. Help!
