Missed period by 2 Days

I was supposed to have my period 21st of April (I use Glow to keep track of my period) But it hasnt arrive yet. When I wipe tho theres a lil brownish stuff ( very little) I get. It doesnt go into full menstrual flow or even strong enough to stain my undergarment. I was kinda hoping that this is it! My OB prescribed Clomid before also Duphaston. Could it be just the Duphaston messing with my period? Mmm. I will wait till day four then I’l tell my gyne, or I shouldnt wait?

So confused. crossing fingers 🤞🏻
