What is this red mark on my breast?

You wrote that your period be late: is in attendance a chance you be pregnant and this was a untimely spontaneous miscarriage? Being a few days late would not “show” any distinct fetus at miscarriage, but might explain the pain, the blood and blood clots (which can look exceptionally much like a piece of meat).
Any adjournment of your period (because of stress, hormonal disparity etc.) can cause brand of heavier and more painful period afterwards.
If you continue to bleed heavily or to enjoy quite a bit of agony with this interval, better go and see urgently your doctor to exclude an ongoing (even worse: ectopic?) pregnancy o some "retained products of pregnancy" etc.
If you verbs with cumbersome, painful period in the adjectives, try anti-inflammatory tablets like Ibuprofen o Mefenamic Acid and consider seeing your doctor to exclude endometriosis o uterine fibroids. Good luck.
