16 weeks and cramps are back

Hi girls, this is my first and last pregnancy! And every little strange thing that I feel scares me off 😕 I know it's common to get cramps in the first weeks because I got them. But, they stopped like at 10th week. Now I'm 16 and they seem to be back. I get them in the morning or nights and when I'm laying down. Can it be normal? They are light cramps not too painful
