I had unprotected sex, and my partner is having one week delay in her period. Is it due to the pill?

Hello,

Welcome to icliniq.com.

I fully understand your concern.

To be very truthful to you, to help you in the future for staying safe, I have the following to tell you:-

Out of the three things mentioned by you, the only emergency contraceptive pill is the one that is known to prevent unplanned pregnancy with clinical trials. Ejaculation or no ejaculation, there is adequate sperm content in the precum to fertilize an egg. So do not rely on the withdrawal method if you do not want to take any chance. The egg may be present even during the relatively safe period, so do not rely on the safe period thing if you do not want to take any chance.

Emergency contraceptive pills work in three different phases, firstly they prevent the release of an egg. If the egg is already there, then they prevent its fertilization by creating unfavorable conditions for fertilization, and if the fertilized egg already exists, then it prevents its implantation in the uterine lining. Yes, you are right that it is one of the side effects of the emergency contraceptive pill to delay periods in certain females, and since you have given Unwanted 72 within 12 hours, it can be taken to be 99% effective. So you need not worry about pregnancy. However, I request you to share the details of your partner's last menstrual period and if she has any history of irregular periods. Also, it will be good if she can take a urine pregnancy test with the first urine of the day for an accurate result. Adhere to all the guidelines written on the package of the pregnancy test kit. Do not drink too much fluid prior to the test. 99% she should not be pregnant. And with withdrawal and the relatively safe period thing, we can take it to be almost 100%. Do not worry. I am always there for you. Feel free to ask any questions or to share any additional information.

God bless.

Hello,

Welcome back to icliniq.com.

Thanks for the additional details. With the two unreliable birth control methods, i.e., withdrawal method and safe period accompanied by one highly reliable method of the emergency contraceptive pill, the likelihood of pregnancy is less than 1% or rather it is not there at all. Also, since the ECP was taken on the 17 or 18th of this month, you can wait for a week more for the periods and then take a urine pregnancy test if required, as I feel the delay in periods is most probably due to ECP.

Take care, and God bless.
