Health issues and dizziness?

So I am currently on my period but at work. I’ve noticed I’ve been feeling a little dizzy and my fingers are a little tingly. I set up a doctors appointment but it’s not for another three days! I’m young and in good health and I don’t have any conditions from what I know of. Im just very nervous about what the Dr is going to say in a few days, and I guess just looking for some reassurance. It’s kind of odd for someone who is young and healthy to have circulatory issues. I was just wondering if maybe anyone has also experienced this or can ease my anxiety, I’m going to ask them to look at my heart. 😭
