You're pregnancy

Lisa
For women who've had a singleton before and have carried or are carrying multiples now, what stands out as being unique or different from carrying a singleton? 
For woman who've just carried or are carrying multiples, what is your special thing you experienced with them in pregnancy? 
I have a four year daughter and she was a pretty laid back pregnancy not many symptoms. A few kicks here and there I remember. At 12 weeks with twins now I'm still throwing up, have a constant headache and swear I feel them at night just before I fall asleep. So very different. I would love to here you ladies' thoughts! 😊
