What careers deal with pregnancy?

I’m a 15 year old girl. I really want to earn my way into the medical careers. Currently I am an A student, though math is definitely one subject I struggle in. Ever since I was about 6 years old I’ve been intrigued my pregnancy, babies/infants, and caring for people in general. At about age 9 I became interested in learning about the human body, especially periods, pregnancy, and woman health. I also have an ultrasound picture from a family friend of her baby(actually from the hospital!) and I love studying and staring at it. I’m also reading pregnancy books,I love the information. All I ever want is to help bring babies into the world, take care of newborns, and give assistance/educated pregnant women. As only being a sophomore in high school (2nd year) I am completely lost in job choices. The only thing that comes to mind is an OB/GYN. That honestly is my dream, but schooling is quite expensive and I’m scared to the whole long schooling/medical school being difficult.

What career choices pop into your mind while reading my description? What’s under a ob/gyn?
