First Time being Pregnant

So today I just found out I was pregnant. With my period being weird one month them being normal AGAUN for the last two months I figured I would wait for a bit before I took a test.. as the last time I did it came back negative.. Now that I know for sure I am

I'm nervous, happy, excited, to be honest a little scared. I have no idea how to go about setting up a doctors appointment for all this.. if like some advice please! Any kind of advice for a first time mommy would be appreciated.
