I need advice on feeling unwell

I’m currently 15+4weeks and I’ve struck down with a horrible cold which is slowly getting worse…

I’m congested

Headache

Cough

Ulcers in my mouth

The cough is killing my chest and really straining my belly, not being able to breath is making the cough worse.

I haven’t eaten anything as have zero appetite and when I do I throw it back up I’m trying to keep my fluids up but that’s not going well been to the pharmacy and the only thing they advised was paracetamol.

Anyone have an advice to help me feel better?
