OV watch tells me fertile day 1!!

Yesterday I got my fertile day 1.  I am so happy it told me something.  I BD'd yesterday and I will continue for the next few days.  I am also using instead cups, they are supposed to hold the semen closer to the cervix and you can keep it in for up to 12 hours.  I googled it and it seems like it is used often to help conceive as well as for your menstrual cycle.  Seriously I think I am going crazy, but without doing something I feel like I am so out of control.  I hate that feeling, if I can do anything I will at least try.  If I'm going to go off caffeine and sugar I can do this.
