Measuring ahead with twins?

Mel

I’m just curious how far ahead was everyone measuring with twins? Did this vary during the pregnancy?

I went for my first prenatal appointment this week at 17 weeks with twins and was told I’m already measuring 23.5 weeks.

This is apparently nothing to worry about according to the MFS, given it’s twins, but I can’t help but wonder how far along will I be measuring by the time they’re born!? 😬 😅
