[|Human|] My wifes last menstrual period was 7th December. Her period is regular, between 28 to 32-day cycle. We have two children and the last one is 5months old. We use condoms as contraception. The first time we had sex in that month was on 25th December and we didnt notice and condom breakage. We observed that the condoms slipped off on 2nd Jan as well  as on  the 4th. No semen leakage was observed but she took postinor 2 on 3rd Jan as emergency contraception. We are worried perhaps shes pregnant but serum ChatDoctor done on 8th January was negative. The registrar in Obs&Gyn prescribed Primolut N for 5 days. We are worried of the contraindications: lactation and suspected pregnancy.  Can we rely on thee serum ChatDoctor considering her period ?. Please I need to know your opinion about this. Thank you.
[|AI|]  Hello, After using emergency contraception, the next normal period can be delayed by a week or two as the excess hormone in the medication disturbs the normal hormonal balance of the body. Since your wife consumed two tablets too soon, the effect would be more. She was in the fertile period around 25th December and if there was a contraceptive failure and if no other precaution was taken, there is a likelihood of conception. This can be diagnosed by taking a serum beta-ChatDoctor around the expected period and in your case, you may need to repeat the test after a couple of days and go for a trans-vaginal sonogram also. Hope this helps.
