Hello and welcome,
If you are not sure then she may go ahead and use the pill. It must be used within 72 hours after unprotected sexual episode to be useful.
The commonest side effects are nausea
. Others include breast tenderness, headache, and diarrhea
in a small group of women. Irregular periods
, irregular bleeding or spotting and change in the date of the next expected period may occur after use of pill.
So you she may use it keeping in mind the above effects. If vomiting occurs within 2-6 hours after taking the pill efficacy may be reduced.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
