Obsessed: staring constantly at my calendar

I'm ttc and I stare at my percent during fertile days, mentally calculating when the best time would be to have sex, then going back to stare again. I check and recheck my days a couple times an hour. I feel cramps and think, SEX! SEX NOW. Then I think, nope, it's better to wait. This baby fever is so crazy. I don't like not knowing. I don't like obsessing. I really wish I was on my TWW so that I can stop wondering if everything I am doing is enough or too much! This would be my first child, and I am obsessed.
