Delayed Menstruation and Side Effects of Menstrual Delay Medications

Menstrual delay medication

Hello; my menstrual cycle usually starts around the 13th of each month.
Due to travel plans, I began taking emergency contraception on the night of December 9th, after having sexual intercourse.
I took the last dose on December 17th, and today is the 20th, but my period has not arrived yet.
Is there a possibility that I could be pregnant? Additionally, I have noticeable swelling in my face and feet today, and I gained three kilograms during the medication period.
Could this be related to taking the emergency contraception? Thank you for your response.

Hello! It seems you are experiencing some concerns regarding delayed menstruation after taking medication to postpone your period. Let's break down your situation and address your questions.

Firstly, it's important to understand that medications used to delay menstruation, such as hormonal contraceptives or progestins, can indeed affect your menstrual cycle. These medications work by altering the hormonal balance in your body, which can lead to changes in your menstrual cycle, including delays. Since you mentioned that you started taking the medication on December 9th and had your last dose on December 17th, it is possible that the medication is influencing your cycle, especially if your period typically arrives on the 13th of each month.

Regarding the possibility of pregnancy, if you had unprotected sexual intercourse before starting the medication, there is a chance of pregnancy, especially if ovulation occurred during that time. The effectiveness of menstrual delay medications can vary, and they are not 100% effective in preventing pregnancy if taken after ovulation has occurred. If your period does not arrive soon, it would be wise to take a pregnancy test to rule out this possibility.

As for the symptoms you are experiencing, such as facial and leg swelling (edema) and weight gain, these can be side effects of hormonal medications. Hormonal changes can lead to fluid retention, which may explain the swelling and weight gain you are noticing. It is not uncommon for individuals to experience these side effects when taking hormonal treatments, especially if they are new to such medications.

If your menstrual delay medication is causing significant discomfort or if you have concerns about the side effects, it is advisable to consult with a healthcare provider. They can provide guidance on whether to continue the medication or consider alternative options. Additionally, if you are experiencing severe swelling or other concerning symptoms, it is essential to seek medical advice to rule out any underlying conditions.

In summary, while it is possible that your delayed menstruation and associated symptoms are related to the use of menstrual delay medication, it is also important to consider the possibility of pregnancy if you had unprotected intercourse. Monitoring your symptoms and consulting with a healthcare professional will help you navigate this situation effectively. Remember to take care of your health and seek support when needed.
