Low blood pressure 96/75

Apparently to Google that’s considered hypotension. I’ve just had a lot of nerves and anxiety since finding out I’m pregnant last night (obviously so happy after years of trying) but my heart cant stop racing and just wanted to make sure that’s normal or common in early pregnancy? I’m 4 weeks.

What are things I can take or do to calm myself? I’m praying hard 😂🙏
