Hi guys! Went to the doc took a blood test was negative 2 weeks after took home 3 home tests were all positive went to the doc again he was surprised that I got positive tests he did a scan nothing show uterus was empty. Went home took another test the next morning was positive started bleeding the next day brown/orange mucusy blood then went to a gynae he did an internal ultra sound uterus still empty can anyone advise if it has happened before?
