What should I do next?

So I’m brand new to this so please bare with me,no received this last night, and I don’t know when I can take a digital to confirm? Also when should I make my first appointment? And has anyone went to planned parenthood for any of this? I don’t have a regular doctor, who do I contact? What are the possibilities of a false positive? I’ve taken like 10 but I’m just worried. Thanks in advance
