Get to a doctor - don't mess with this sort of thing.

Would be pretty **** to get a severe kidney infection and not have seeked help and then have some kidney damage as a result which will really impact your health and your TTC.

Book and appt - even if it is in a few days and get it checked - once you know what it is you can start making decisions about drugs etc but until you know, you are risking your health and that baby you want would like to have a really healthy body in which to grow!
