I completely agree with Spiderman74 and TheLastTime!!! Don't listen to your woman because it is all subjective. How do we know she doesn't work in Labor & Delivery when she made the statement ,"This is not the place for you." And actually, even though it is not for me...I remember seeing men in OB/L&D and Women's Health. If it is what you love, go for it! What used to drive me insane is that some people had issues w/male nurses in OB/L&D, yet they had male OB/Gyns. Makes no sence, but off topic. Lastly, all you need to know is med math. You are not studying engineering, or finance. I took calculus in college (since I made a career change too), and we never learned anything in nursing school nearly as close to that type of advanced math (including Trigonometry, Algebra, Adv Alebra., Geometry, etc). Good Luck, you can do it!
