Walk I am so sorry you and your family are going through this and hope it does end with good news.
Getting sorry you are spotting again and hope it goes away for good.
Snowflake that is a good idea to get second opinion as I got four different lengths, one been 5mm, 27mm, 18mm and now 35mm but I was also shown on my scan that there was over 1cm gap in my cervix when there shouldn't be and that I would be lucky to make 22 weeks. It just does not make sence to me.
