on the way to RD? or maybe RN?

Hello everyone! I hold my bachelors in nutrition and a masters in sports nutrition from Spain. Therefore, I only have to take some classes (for the DPD) and then the internship to become RD.

Just started my second semester and I am starting to doubt. I work for the WIC program as a nutritionist. I am really liking breastfeeding and I became a CLC and would love to be an IBCLC. But now I am not really sure if I wanna work towards the RD, or maybe better move on to the RN, since it’s going to open a lot more doors and I dont think I dislike the job.

For people that hold a bachelors in Dietetics or RDs, how long did it take you to become an RN?, How much did it cost you? And how do you like it?
