Husband feels used for sex

Ok, been TTC for about five years now, (not all years with him). We been married for about a year and six months and we’ve been trying for about almost 2 years and nothing has happened. Yes I got all the test done all the test you can say I got it all done and he also got tested and his sperm is perfectly fine. But as women we know how much I can take a toll on us I got to the point where I got depressed, but as time was going I got better to where hey it will happen when it happen. (Believer of God). But my husband feels like I use him sometimes when “baby week,” ovulation day time comes. and I’m pretty sure I’m not the only one “using“ her husband when it comes down to babymaking time. How can I explain to him that no baby I am not using you it may feel like I’m using you but you are my babies daddy you’re my husband and we are raising this child together. He just doesn’t understand infertility and what us women go through when it comes to that time of the month. HELP! Of course I’m not using him but yes in order for me to become pregnant I have to have sex with my husband. I always try to make sure it’s intimate and sexy but at the same time I want to be a mom. Help me to explain this better to him. Love u guys. Baby dust!
