Im pregnant now what???

So my husband and I weren’t trying, but have managed to create a miracle. We have only been married about six months and so I’m a bit scared and very confused and unsure about what to do now?? We are waiting to tell family until we have waited out at least a month just to be sure it’s not a chemical. Plus we live out of state from them so we don’t see them until thanksgiving, SO when should I go to the dr? What should I avoid as far as eating/ doing (I don’t drink or smoke so that’s not an issue) ANY ADVICE IS EXTREMELY HELPFUL!
