Getting annoyed

Callie
AF hasn't turned up!! My calendar is full of love hearts. Why a bfn!! 
Been ttc for over a year and half now. Starting to get annoyed. I was on the depo injection for 5years before coming off it 2 and half years ago. Had scans early on showing I had cysts and a blockage. Then irregular periods. Had another scan few backs back al back to normal. Really thought this was the month. Trying not to stress or worry too much.
