Has this happened to anyone else before?

Hey ladies! My period last month was definitely unlike any other period I’ve ever had. Around my third day I started experiencing some dizziness and being off balance because of it. Usually my sister has these symptoms on her period but it leaves after her period ends. For me the symptoms continued after my period to the point that all I could do was sit/lay down all day to keep from falling over and walking in one direction. But after a few days of being off of my period and being this way I started having heart palpitations. I have had heart palpitations before in the past, but these were different and made me feel as though my chest was extremely tight and hard for me to breathe in and out completely. It’s been officially two weeks since my period passed and my next one isn’t due until the middle/end of this month but now I’m experiencing pains in my chest and palpitations because of sudden feelings of anxiety. I recently talked to one of my closest friends about this and when she was on her period she told me she was feeling the exact same way as well. So I was wondering if anyone else has had this or has felt this way during/after their period as well. It’s definitely a first for me and I’m dreading my next one because of it.
