Should I get RN certification in OB or EFM?

[lola_b123]

I am interested in getting a certification. I have nearly 3 years experience in L&D and did 3 years of couplet care prior to that. I could either get a certification in OB or Electronic fetal monitoring, but not sure how to pick between the two. I appreciate any advice anyone has to offer. thanks in advance.

I got my RNC-OB certification first, then did C-EFM second. I'd say get either one first. If they're both paid for, why not both? If only one is paid for, get C-EFM first.
