Oh god, the dizzy spells are so real! Sometimes I feel like I'm on a merry-go-round just by walking from the sofa to the kitchen. I've basically accepted that my couch is my best friend now, haha!
Haan, dizziness is common because of hormonal shifts, but don't just ignore it. Keep yourself hydrated and don't stand up too fast from the bed. If it's happening too often, go see your doctor instead of sitting at home.
I remember feeling so lightheaded during my first trimester, especially when my stomach was empty. I started keeping a few biscuits on my bedside table to eat before getting up. It helped a lot, but do mention it to your gynac.
Actually, low blood pressure or low sugar can cause this. Keep a bottle of nimbu paani with a pinch of salt and sugar handy, and drink it slowly. Also, never skip your meals, simple home food is best.
My mother used to make me lie down on my left side whenever I felt dizzy, and she would gently massage my feet. It really helped with blood circulation. Take plenty of rest and let your family pamper you right now.
