Infection after lletz?

Hi just asking for a bit of advise.

I had my lletz 2 weeks ago tomorrow.
Everything was fine. Had my period 3 days after when I was due and that ended.

Since then I had a funky smell for a few days which how now faded so I ruled out possible infection.

Yesterday I took the dogs for a decent walk and noticed that I had bright red blood. Not a lot at all. The size of a 50p I would say and had slight tummy pains. Like period pains and that went off.

This morning I have woken up not feeling very well. Like a chest infection and head ache. Could a chest infection be related to infection after lletz? It like a typical chest infection hurts when I breath in an swallow.

Any advice please. I can’t phone docs ad it’s a Sunday x
