aww.. I'm sorry girl..
First off let me say.. the shots aren't as bad as you think!! The anticipation is the worst part! Wait til you get that shot over with.. You are going to be so proud of yourself!!
All I can say is maybe your Dh is nervous.. maybe he wants things to work and he's stressed about the whole thing also and doesn't know how to show it.. Maybe it hurts him knowing that you are going through IVF because of male factor and maybe it hurts him knowing you are taking shots because of that reason..
IVF is very stressful.. all i can say is talk to your Dh.. you guys need each other during this.. Its an emotional rollercoaster thats for sure and you need each others support!! hang in there
