Please help me 😥

My husband and I have been trying for almost 6 years and we have been to a fertility specialist and he did a lot of lab work. He did hormonal blood work and checked my eggs and did a hysterosalpingogram, and checked my husband Semen, and everything came back good, my doctor told us to try natural for 3 more months then if your not pregnant then make a appointment and then we will look at other options. I have been taking pregprep, natural blend supplements.i Also bought a clearblue monitor to use my clearblue ovulation sticks, and I also have 2 tracking apps so I have been trying to get pregnant for now going on 4 months after our appointment that we had our fertility doctor appointment. But now our time is almost up and my appointment is this July 12th and I think he would be recommending IVF but we will see. I read fertility books to keep my mind occupied, what would be a good book you would recommend to read for IVF? I don't a little about it but I want a IVF book that would explain everything terms and all and the processes and ext. PLEASE HELP. Also maybe you guys can help what insurance companies accept ivf? I don't have any insurance and looking for one that would accept.
