Go for my RN or Not?

Going back to nursing school a tough decision to make after being out of school for a while. I returned to school in March of this year and I am currently going for my Associate in Allied Health care. I am doing this program online through South University.So far I am holding an A average. It's different because I was a C average student while I was doing my LPN, I do have a few Bs. I guess I did not take school as serious as I should. Now I feel disappointed at myself if I get a grade less than 100.My counselors always give me that pep talk that I am still maintaining an A.

My academic counselor is encouraging me to return to school for my RN. I have all my prerequisites and he informed me that it would take less than a year to complete this program. I started to look at some schools. I have been asking myself if this is what I want to do after I graduate in March 2016.Another field that sparkled my interest is Medical Sonography. I am interested in the obstetrics area of the sonograms. So at this moment, I am contemplating the pros and cons for both. I do enjoy nursing and I do want to continue in the health field.I have some time left to think but one of the nursing schools is accepting applications in July of the previous year for the following fall.
