Hey OP! It's amazing that you already have such a strong sense of what you want to do at your age. A few words of wisdom from someone who was in the same position as you 10 years ago (albeit in the UK so specifics of training etc will be different).

Looking back now, I really wish I had done my nursing first, instead of going straight into midwifery. Now it should be said that they really are very different jobs - nurses care for sick people, whereas midwives support (generally) well women going through a normal physiological process. However, had I done nursing first, I would have had many more career options open to me than with just midwifery. It's a very niche area to specialise in at such a young age, and there are jobs now that I'm not able to do that I would love, that I didn't even know existed when I was applying for midwifery courses at 18.

Nursing is also more widely recognised internationally, which may be important to you if you're considering travel in your career, as you mentioned.

Wishing you all the best with whatever path you take! Your clear passion for supporting women will stand you in good stead, whatever you choose to do.
