Sorry if this is in the wrong place if so I will message MNHQ.
My DD is coming up 5, when I was 8 weeks pregnant with her I had a massive bleed. I had a scan that showed DD but there was also an empty sac. I had to go back for another scan around 10 days later which showed the sac had gone and DD had a strong heart beat.
Nothing was explained to me about this empty sac.
Do you think this empty sac was DD twin or am I just overthinking this after a comment I had.
