In 13th week I had miscarriage.Anyway now I am pregnant again and I went for my internal scan on 13/12/20 my last period date was 13/10/2020 so I suppose to 9 weeks. But in scan she said I am only 5 weeks. 😔 so she said I have to wait another 2 weeks for an other scan. I am so worried. No cramping no spotting. But I am so stressed. Plz share ur experience ??
