Thanks for writing to us.
1) You did sex with broken condom on safe period (on 23rd) and she took emergency pill within 14 hrs, which gives more than 95% protection against unwanted pregnancy
. She has NO chance of pregnancy in this case.
2) She will got a period like withdrawal bleeding on 29th due to effect of the pill and it is quite common phenomena. It will stop automatically without need of treatment. However, next period may be delayed for 1 to 2 weeks.
Hope, I have answered your query. Practice safe sex
in future. Good luck.
