Trying for a baby

So, my husband and I have been trying for a baby for 11months. We just found out he has low motility and we are going to doing <a href="">IVF</a>. However, sometimes i feel like having sex is pointless. Sometimes i want it everyday all day but other days I dont feel like i can be into it. All we want is to have a baby!  Sometimes sex feels like a chore. Anyone else feel like this?
