15 days late for period, negative tests! Started spotting Saturday, bled heavy Sunday one clot. Stopped bleeding Monday but was spotting very dark brown with tiny dark brown clots decided to test and was faint positive, spotting lasted until Tuesday. Bleeding has completely stopped today which is Thursday. Checked cervix and it has been medium height soft and firmly closed. Should I retest tomorrow morning or count it as my period?
