Dizzy spells and feinting

Bump pic just for fun ....

I am 25 weeks and having another lot of dizzy spells and feinting.

I have days where I wake up and then loose vision and have to lay down or I pass out.

I have good days where I don’t get this.

But recently it is happening again where I don’t feel I can be on my own due to safety and I cant drive because it isn’t safe.

My dizzy and feinting spells have been happening on and off since I was 7 weeks and I was really hoping they would have stopped by now.

I have tried eating more and drinking more water, sugary carb foods and heaps of fruit and veg... tried to eat what I am craving

None of it helps and I just want to be able to be more independent ...

Any advice ?
