Sex drive..

I've been having issues getting "aroused" for my husband. He tries a lot to get me to have sex with him but I'm just never in the mood. When we do have sex it's just kind of pointless because it doesn't really seem to feel good anymore. We're TTC so sex is pretty important to us. I feel like something is wrong with me, I'm just never "horny" anymore. Does anyone have this issue or had this issue? What did you do? Nothing has changed in our life except were moving in 3 weeks but this has been going on well before we found out. I just feel so bad for my husband :( please help me...
