Thanks for posting your query at DoctorSpring.com
You do not need emergency medical attention, but yes, you DO need to consult your OB - GYN.
This could be the beginning of a small vaginal prolapse.
It needs to be differentiated from a vaginal cyst or a vaginal polyp.
None of these are emergency conditions and can be treated easily .
So please have an internal exam as soon as you can get an appointment.
Hope this reassures you.
All the best
Please feel free to discuss further.
