Picked wrong unit?

Okay so I am in need of some help, and advice. I'm a nursing student, graduating in May from an accelerated program.

I was offered the opportunity to apply for a internship/ preceptorship last minute a couple of months ago due to last minute changes in our curriculum. I decided to a apply, in hopes of getting good hands on experience and also having a job secured before graduation.

I got the internship, but not in my first choice unit. I chose my top 3 units without much thought being that I haven't spent enough time in any one unit to know what my "niche" was, but regardless was apprehensive and almost declined the offer. My unit choices were NICU, L&D and ICU.

I had a hard time deciding at first between L&D and ICU as my 2nd (and ICU even as my first) choice. Well I ended up with an offer for L&D, which I ended up taking. My coordinator told me that if I found it wasn't for me, he's try and find a position in another unit.

Although I don't hate it, I don't love it and I don't feel it suits my personality. I've spent time on the unit, and even though moms and babies are a happy environment, I just don't feel that I made the right choice as a new nurse.

I could kick myself sometimes, and I believe its a challenging area, no doubt. For me though I feel like I'm not using my critical thinking, and not using pathology the way I'd hope to.

I wanted to train in a Critical Care area to learn as much as I could as a new nurse, and I'm finding that L&D is very specialized, and there isn't much outside of women's services that you could easily transition to.

I'm still early in my preceptorship, and could possibly change if I want to. I met a nurse today though that said she was "put" in L&D but wanted a critical care unit or NICU as well, but ended up loving it.

Any advice?

My dilemma is if I wait to see if it grows on me, and end up not feeling any different from how I feel now, I will either have to work it out for 2 year (contract for internship) or turn down a job offer.
