Need Some Advice

I was only a day late when I took a test yesterday. It came back positive almost immediately. I was in total shock to say the least. I later went back and bought 2 more in a different brand. Took them both and had the same results. The lines weren't even faint. They were bold and strong. I was in a shock and overwhelmed for a good 3 hours. I think that I'm still in disbelief honestly. My husband handled it better than I could have ever imagined seeing is how I've been the one to always talk about kids. I don't want to tell anyone else yet because I'm scared of what can happen since it's so early. So my question is, now that I have 3 positive tests, what do I do now. Who do I call? Who do I make an appointment with. I've never even been to an OB. I think that I'll start being able to come to terms when I have a game plan you know? Any advice?
