Couldn't find baby

Well hi everyone I went in  due to some discomfort on left side . I am according to my last period date 8 weeks . They did a scan and found nothing in my uterus they also did an internal scan and also found nothing . They check my tubes and nothing also they told my uterus looks swollen as if it is growing . I'm crushed as this is my first and was really looking forward to it. I did have irregular periods befor falling pregnant and I'm praying I'm just not 8 weeks . They drew some blood and will be checking my levels  in so sad and feel my whole life has ended
