Enlargement of the vaginal opening by surgery.. Time to remove the surgical thread and maximum recovery period

- Widening the opening of the vagina by surgery and sewing.
The thread still exists although it has been 16 days and I have received the treatment prescribed by a doctor and ended and is currently using the medication Meebo.
When can I remove the surgical thread? What is the maximum recovery period?

- Do not be afraid the string may last longer than a month.
