Am I getting too stressed?

I'm wondering whether stressing so much about whetting pregnant and willing it to happen is maybe the reason that i can't get pregnant at the moment? Does anyone have any tips to calm the baby fever and help me relax a little. Every time my SO and I do the baby dance I'm like "yup I feel it, definitely pregant" and then I get a BFN and get really upset :/
