overwhelmed

It's only our 3rd month of TTC, and I know others have been trying much longer, but I feel so overwhelmed by everything. There's so much to track and think about and time out, that it stresses me out and makes me anxious. It completely kills any mood of wanting to be intimate because all I'm thinking about is will this be the time, am I ovulating, why hasn't it happened yet, is there something wrong with me that it's not happening...Any advice on how to cope with the frustration and feelings of being overwhelmed?
