Urgent - Smell one month after Lletz

Hi all! It's been 4 weeks since my Lletz and last week I've noticed a funky farty smell lingering. My discharge doesnt smell and it's creamy and normal.  I thought it was my boyfriend has he had been trumping (lol) or my baby pooping but today on train it was neither! I had infection few days after.

Is it normal to have potential infection one month later? I have no other symptoms! Last time it was smelling stronger. Could it pyscho-symptomic. Or whatever the word is. 

I got an infection 3 weeks after lletz, no smell I just hemmoraged which they said was caused by infection interrupting the healing process. That smell doesn't sound right so I'd def go see the doctor x
