Almost blacked out on period?

an

So I had a cold that I got from my husband. But it’s been wearing off. Just left is the sniffles. While this my period started. Usually on day 2, is where I experience the worst symptoms. On this day we had lunch and dinner with our lovely neighbors who are like family to us. At the end of the night, During mid conversation as I was sitting down, the room started spinning, a high ringing in my ears started and as if I blinked without actually closing my eyes the room went black and the immediately turned back on. It didn’t last long cuz I was still finishing my sentence. Not even sure how I was managing words out of my mouth. Immediately after I had to place my head down on the table to prevent myself from losing it. And I said to my husband “I need your help to get home”. I don’t know if they saw that I was blacking our or what. They were concerned. Anyway, do any of your periods get this bad? This happens to me once in a while. Maybe once every 2 years or so on my period. And it can be scary.
