Regular, 22 dpo, 9 days late, still faint positive on hpt.23dpo af came with clots&tissues.pregnancy/miscarriage happened? or just late period?

Either is possible.: Either is possible, but a blood test at that time would have given you the answer possibly if the pregnancy hormone (HCG) was still elevated.

Preg test +: If your pregnancy test is positive and now you are experiencing bleeding then you need to be seen by a doctor. If your pregnancy test is positive then this is not a menstrual cycle. A miscarriage is the most likely but ectopic pregnancy must be excluded.
