Pregnant, now what??

I got off birth control month ago. I thought my period would be weird for the next few months and didn't think much of it when I didn't get. After two days I took a test just to rule pregnancy out, but to my surprise, it was positive!
​Now I'm not sure what to do?? I know I need to take prenatal vitamins, but do I need to go to the doctor?? Help this newbie out!
