FTM baby kicks...

Destiny • 22 years old and pregnant with fraternal twins! Due late April! So excited! My first child/children!
So I know usually you don't feel baby kicks until about 24 weeks. But I am pregnant with twin boys and randomly throughout the day I will feel a very small part of my stomach jump. I don't have hiccups at the time or gas and it's one then another about 5-10 minutes later. I don't know if this is like a muscle spasm or a baby kick. Where I am feeling these movements is exactly where my babies are located. Any help moms? I truly hope it's baby kicking but I don't want to get excited over something if it's just my muscles jumping and spasming.
