• As part of the investigations that I will offer you during your first consultation, a low vaginal swab test (like a cervical smear but from the lower part of the vagina) which you can do yourself. The sample is then sent to the lab. for analysis. The result usually becomes available within 24-48 hours. If the result confirms that you have BV, then I will offer you antibiotic tablets called clindamycin or metronidazole. By having one of these drugs during or before pregnancy the number of late miscarriages are dramatically reduced.
