Can I use Urosept in pregnancy?

I am in 16tc, such I have current urine results, a visit to the gynecologist in a week, can I support myself with urosept until then? With such results, is it better to take an antibiotic and speed up the visit? And what do such high ketones mean? Since glucose is negative Could this be a suspicion of diabetes? In this case, is it only due to too long a break in eating? I will add that I feel a little discomfort when peeing
