Preconception Hypochondriasis

Since we've been trying, I have become hyper sensitive to every body function and sensation that could possibly indicate pregnancy. I'm constantly looking for signs and symptoms: "I'm so tired!" (Nevermind that I didn't get any sleep last night, maybe I'm pregnant?) "Was that a wave of nausea?" (Or maybe I just need to eat something?) "I have a headache!" (Is that a sign!?) "My big toe hurts!" (Well, probably because I stubbed it on the couch.)
