What is Leucocyte + + +

So at 28 weeks 6 days had a consultant appointment for my 28 week scan they did a urine test at the appointment and the consultant has put I have Leucocyte + + + on my online maternity notes which I’ve only just logged into, as they said everything’s fine so I’ve just logged into double check my midwife appointment time for tomorrow and saw this i will be asking my midwife tomorrow what this means but can anyone tell me what this could be as it’s kind of worried me what this means or that I could have something and I’ve not known for 4 weeks, I don’t no if I’m being silly but I just think why hasn’t my consultant told me
