One thing I can tell you is that it's very possible this isn't related to your period. It sounds like you almost passed out - that's why your vision went black and fuzzy. Whatever happened to you sounds concerning and should be addressed by a doctor.
Another thing I can think of is anemia
, which is when your iron levels are too low. Do you have heavy periods? If you are losing too much blood, you are losing a lot of your body's supply of iron. Anemia can cause dizziness
, excessive tiredness
, feeling cold, shortness of breath
, and feeling light headed. This is because without enough red blood cells, your body can't deliver enough oxygen
to your brain and body. You need to go see your doctor as soon as you can. Anemia can be helped by taking iron pills, but it could be something more serious.
