Missed Period and now passing clots.

Leresce

Good evning . I was 3 days late on a period which supposed to start on the 25th. I am on a 23 day cycle and its very refular. I been passing blood clots from the 28th May. When pee i would see it in the loo and when i wipe some blood would come out but it is not enough for me to wear a pad. The clots small . Any idea whats happening. I havent taken a pregnancy test as im afraid of disappointments and i dont know if this is considereda period.
