Hoping for twins!

I lost both grandparents in the last couple months and actually found out the day I lost my grandma my husband and I are expecting our 2nd child. Both grandparents lost were twins. 1 was paternal grandpa and maternal grandma .. Now all I can think is how amazing it would be if this little one ended up being a twin! I am experiencing a total opposite pregnancy this time with my daughter I puked up until 15 weeks. Hardly any symptoms this pregnancy except heartburn and breast tenderness ...
