6 months pregnant

Idk what to do. Always feel dizzy after eating meal. Hirap dumighay. So after eating, lagi ako sumisipsip ng candy. Not just once but more than 10 or 20 candies ata a day. Mas lalo ako nakakaramdam ng hilo if i walk or kahit nakaupo ?. Need talaga nakasandal ulo or naka slant ng higa kase baka sumuka ako if hihiga agad ako. Help pls ?. Anemic ako pero umokay nako eh. Pero ganto nanaman feeling ko. And i hate it. Gusto ko nalang forever nakahiga ?
