Whether or not you can have intercourse the next day after vaginal plugs the night before depends on the circumstances. If it is used to treat inflammatory diseases of the vagina, such as mycobacterial and bacterial vaginal inflammation, intercourse is not allowed in this case. This is because the inflammatory disease must be treated according to the norms and intercourse during the healing of the inflammatory disease may cause cross infection, so intercourse is not allowed in this case. Even if there are no more clinical symptoms, then after 3 days of the last plugging, you need to review the leucorrhoea before having intercourse. This is because in many cases the bacteria may be carried, but the clinical symptoms are not obvious. If you are treating chronic cervicitis or using Lactobacillus vaginalis to regulate the vaginal flora, you can have intercourse if you are separated or have to have intercourse due to unforeseen circumstances. However, it is best to use water or some lotion to flush out the vaginal drug residue before having intercourse. If it is not urgent or emergency, it is better not to have intercourse, and it is better to have intercourse after 3 days.
