No appointment until 9 weeks

I just found out I am pregnant (five weeks) I scheduled a dr appointment but they told me they don’t schedule until 9 to 10 weeks. I know that this is pretty normal but I am feeling like I have so many questions that I want answered before that. I feel like I am just constantly googling things and not finding straight answers. For example, can I keep taking the vitamins I currently am? Do I need to cancel my hair appointment (dye)? It’s giving me a bit of anxiety that I am going to end up doing something wrong, or not be doing something I should before I actually get to my appointment. Did anyone else feel like this? I feel like I have no clue what I’m doing.
