Orthodontist Jobs

I am debating which one between on getting pregnant or pursuing an Orthodontist Jobs for next year. I've been wanting to have my own kids since right after few months I got married to my husband and for this year we will be celebrating our 5th year anniversary. I got hooked with my job right now that I am not in a feeling yet to resign, by that it made me change my want of getting pregnant. But on the other hand, I want to go to school to make what I do be a better career for me. I just want to have them one at a time so I won't get overwhelmed and regret, which it's never be my optional.
