Ladies I need advice😓

So I spent 2 nights in hospital for them to the me I had reflux (now I've had reflux before and know what its like) I've been home since yesterday morning and my breathing is worse, I went to see my doctor last night who said it was normal pregnancy symptoms so I asked yo get a ventolin to try help with my breathing. I've taken it 3 times within the last hour and it only makes me feel better for 5 minutes. I understand that dizziness and that is normal but I don't think to the extent that I can't even breathe normal sitting down, when I stand up it's worse and I get dizzy and can't walk straight at all my whole body is weak. I haven't been able to drink much fluids because it makes me feel awfully sick. I'm worried about my health affecting my baby 😓

should I go back into hospital or not???
