My date was 2 days before but my periods hadn't came, rather I'm having bloody mucus clots slightly brown red in colour that are limited upto vagina only, aren't coming out but I'm having same cramps like periods and feels like they've came, but not. I am physically active and doubting if anything has gone wrong. Also from last 2 cycles my cycle has decreased from 28 days to 23 days suddenly, I'm assuming this stress, please help and tell me what should I do
