I hate UTI’s, I have dealt with them frequently my WHOLE life…I was more prone to them during pregnancy and with my last I was on antibiotics for several months on and off…the best way to know if you need to have your kidneys checked out is if you are having pain in your back, basically where your ribs are but on your back, it will be a dull throbbing pain and you can feel where it is traveling from your bladder up your sides…at least I have gotten so used to the pain that I have learned how to tell, my UTI’s travel to my kidneys in a bout 24 hours time…ugh…anyways you can buy cranberry pills over the counter and I now take them every day, there is something about cranberries that lines your urethra and prevents bacteria from sticking, what I think you should do is keep some baby wipes in your bathroom, every time you go to the bathroom clean down there really well, from front to back, if you are sexually active clean down there immediately before and after sex and make sure you go pee after asap..call your doctor, if you have a UTI take your antibiotics until they are gone, take them on time, don’t miss a pill, even if it starts feeling better you need to finish them as directed, take cranberry pills and pay close attention to your body and note any back pain where your kidneys are located….I am not a doctor so this shouldn’t be taken as medical advice, just from one person who HATES and deals with UTI’s constantly to another….I hope this helps a little bit!!
