Bubbles/gas escaping from vagina when i lie down?

Disturbing: If you indeed have gas or bubble from the vagina, you should be seen by a gynecologist and examined thoroughly. This may well depend on your age and if you have had surgeries in the pelvic area, child birth or any instrumentation "down there". You may have developed a communication between your colon and your vagina (colo-vesicle fistula) and this needs attention. This can happen to the bladder.
