Hey ladies

So This is my first pregnancy I’m 23 + 5

So last couple days I’ve been getting really dizzy! To the point I have to sit down I come over feeling really nauseous feel hot and sweaty my vision goes abit odd for a few minutes & if I don’t sit down and let it pass I feel like I’m going to collapse! Then once it passes I’m fine again!

Today This has happend 4 times in the past 2 hours

Any ideas? Is this normally or should I be coming concerned?
