TTC; problem or normal?

So January I came home from a week's long vacation with my dad's side of the family (divorced parents) and my husband and I were having welcome back home sex and right before he came he tells me he wanys to cum in me and thaar hes ready to start trying to have a baby. So we didn't talk about it for a couple days because I didn't know if it was an in the moment thing or if he was serious and I didn't want to cause an argument. So fast forward, we talked about it and start trying. So far no baby and on and off slight depression because every time I open up Facebook someone else is finding out their pregnant, even though I try to remind myself it'll happen when it's supposed too and stay positive. Sometimes I just can't keep the depression away, so the last time I actually had a spell, I suppose we can call it, I ordered fertility assistance pills. Because I feel like it's my fault. But my husband refuses to let me believe it's mine and tries to say it's his because of when he was in the military.. I'm so conflicted and I just want us to start our family already. I also don't really have anyone to talk to this about either..

Has anyone else had these problems?
