A day late and on Clomid

Hey guys, long time reader first time poster. This is my 4th month on Clomid/Metformin/Myo-Insitol combo and my periods are like clockwork on this treatment. I know exactly when I ovulated and my period is a day late. Every cycle is 30 days and 2 yrs ago I did four rounds of Clomid only and my cycles were 30 days then too. I had a devistating miscarriage though a few years ago and what I'm getting at is that I really need someone to tell me to relax and not get my hopes up or get too excited because I haven't taken a pregnancy test yet and I'm freaking out.
