Hello,
You had unprotected sex with your wife and she took Postinor 1 and 2 pill as a precaution. If she took
emergency contraceptive pill within 72 hours of
unprotected intercourse then she should not get pregnant. Emergency contraceptive protection is a one time use medicine. Delay in
menstruation commonly occurs due to changes in
hormonal due to the pill.
Other medical conditions that may cause delay in periods are stress(emotional or physical), anemia, PMI, premature ovarian insufficiency, low body weight, obesity, thyroid problems, PCOS, etc. If she misses her periods, she can get a
pregnancy test done with the first, morning, midstream urine. Get her examined by a gynecologist, she needs a per vaginal examination done to detect bulky uterus. She may need a USG done to rule out ectopic pregnancy. She will be managed accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
