Trying and no luck

My fiancée and I have been TTC and we track everything right down to when I ovulate I have had two children from a prior marriage but that's besides the point! I have been stressed to the max over everything and anything and I need some kind of distraction or something that can take my mind off of everything that is going on right now. We have been trying since July and nothing yet and it is making him think that I don't want to have a baby with him but he is completely out of his mind because I really do want another child mine are 8 and 5 and the oldest has a birthday a week before Christmas I just need some help ladies what can we do!!! ?✨??
