Movement at 12 weeks?

Ftm here so don’t judge please. I was 12 weeks exactly yesterday and I also had two people (who already had kids) if I had felt any butterflies. I always thought it was too early but my pre pregnancy weight was under 100lbs (still technically healthy, I’m just small) and today I’m sitting st my computer working and in my lower abdomen around where baby implanted, i felt what felt like little bubbles or I guess you could call them butterflies? Is that actually possible?
