13 week flutters??

Jordin • Marrying the love of my life💓 First time momma to be July 2020❤️

I’m 13 and a half weeks pregnant with my first. I’m about 5’3” and weigh about 113. I’m had these flutters in my lower abdomen for the past few days, especially laying down not doing anything. Baby is super active on the ultrasounds that we have gotten recently so I’m wondering if the flutters are the baby moving ???
