I am 9 weeks pregnant, i had an anxiety attack and my heart beat extremely fast i was able to get calm, but i am so worried this will harm the baby?

Get treatment: I don't think it's likely that an anxiety attack will hurt your baby, but it certainly can affect the quality of your life. I would recommend seeing a mental health professional who can help you get your anxiety under control, as well as learn coping strategies. I would want them to assess if it was just anxiety or a panic attack. I also think you should mention it to your treating ob-gyne.
