Lightheaded?

Bárbara • I'm 28, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!

Is it normal to feel lightheaded?

I'm 27w6d. I'm nervous because I never felt like this and it's not like I'm doing stuff, I was just sitting and I started feeling like this! Anyone had this? Thanks ^^
