Krystal - Im sorry your doctors have let you down. You will see from reading the forums that care is different for every woman that is coping with IC. This is because there is no standard treatment. Every woman is managed differently.
I am a doctor, married to another doctor (who's speciality is OBGYN) and am also 37 weeks pregnant with my second pregnancy and have had two stitches. The first one got infected and I lost the pregnancy, this one has not and I hope to be having a c section soon.
I have read a huge amount about the subject and don't pretend to know it all - not at all - but I can try and offer you what I have learned in the process.
Firstly, you cannot tell exactly what infection may be in the vagina and cervix from the urine sample.
The vaginal tract (area) and urinary tract (bladder, kidneys, ureters,urethra) are two separate areas but share some of the same bugs.
Some infections may contaminate the urinary tract and bladder as well as the vaginal tract - but you cannot say that the vaginal tract is free from infection by relying on urine samples. Yes, you can detect some infections via urine - but dont rely on this method. You can get infections in the vagina that dont show on urine culture.
In some cases, Urine samples can be used to see if a specific infection needs treating during the pregnancy. For example, with Group B strep - if you are a carrier, it is usually present on vaginal swabs and needs no treatment until delivery. If however it is detected in urine, it will need antibiotics as thought to be more invasive and has spread into the urinary tract. This shows the infection is becoming more aggressive.
I would start taking the vaginal pessary now and continue daily for 3-6 days.
This is how I managed my second pregnancy:
I took oral fluconazole prior to getting pregnant.
My husband did also.
My husband has continued to take it through this pregnancy.
I had an elective stitch at 14 weeks with IV antibiotics.
I took oral fluconazole (one dose only) 1 day after the stitch.
I have had vaginal canestan pessary tablets weekly since the stitch.
I have not had any baths/gone swimming etc
I have tested my urine at home with sticks every week and sent a sample off every 6 weeks for culture.
I have had swabs every 6-8 weeks.
Sarah&Ady - Sorry i think didnt phrase my last post well. was in a bit of a rush. Im not saying testing urine is a waste of time - because its not at all. But If you want to make absolutely sure that you are infection-free, it is necessary to do both urine culture and vaginal swab culture. This can be repeated regularly or earlier if you develop symptoms.
Of course not everybody gets thrush with antibiotics - but people who are prone to thrush do have a tendency to develop thrush when the normal bacterial flora of the vaginal tract is eradicated by the antibiotics. I am one of these people and its quite common.
Every woman is different and treatment plans vary a lot. But its really important to get as much information as possible from different women and from different doctors - and also have the balls to say that you are not happy with the current plan and want to be swabbed etc.
