Hi mommy. I think it depends sa doctor but some are allowing to try it nainormal if hindi bubuka iyong tahi mo mommy. I have a friend, 10 years nga lang cs then the ob allowed it na inormal kaso bumuka ang tahi ulit. In your case naman mommy, 18 years. Pero better to ask your ob. š
Depende parin po š
