is it her or am i crazy?

Hey so i’m 18 weeks pregnant with my first baby. About a week ago i began feeling her move. People and the app say it’s too early especially with your first pregnancy. But when i lay on my back i can feel movement/kicks through my stomach with my hand. I can also feel it on the inside. I feel like i must be imagining it since she’s so small still and i was told i have an anterior placenta which means i wont feel movement till much later. But the movement/kicks is honestly so strong. Is it the baby? Or am i imagining it! i feel crazy!
