What would you do if you were pregnant for the first time and you just found out you're having triplets?

I'm 19 years old, and I'm 12 weeks pregnant. I was obviously expecting to find out I was having a single baby at my ultrasound, maybe twins, but not triplets! I'm a little overwhelmed with my situation, but I feel blessed to be carrying three little miracles. I'm excited for the journey ahead, but I do have a few questions for the community.
