That happened to me as well today and lately.... It's really scary. I thought my hearing and vision was going away. But both times I was outside but I felt cool so I don't know what it could be.
I read that it could be part of pregnancy....my advice would be to just take it easy for a while and if things don't get better Exp if it happens again call your doctor.....hope everything is well with you :)
It could be low blood pressure, make sure you let your care giver know, and if it keeps on happening I would think about going and getting checked out, bub should be ok though
Lightheadedness and fainting can be common during pregnancy. Sometimes it is due to low blood sugar, and sometimes it is caused by moving to fast or standing up too quickly. If it happens alot then you may want to go get checked.
