Vaginal Bumps and Menstrual Delays After Emergency Contraception

Genital issues

Hello doctor, on the night of December 15th, while taking a shower, I noticed a round, raised lump near the vaginal opening that wasn't there before the 15th.
There was no bleeding when wiping after using the bathroom.
Could this be genital warts? Additionally, I have a question regarding an incident on November 2nd when I had sexual intercourse with a condom and took emergency contraception, but my period is now a month late, and a pregnancy test showed negative.
Is it normal for the emergency contraception to delay my period for such a long time? Thank you for your explanation, doctor.

Hello, the lump you mentioned cannot be assessed based on your description.
It is advisable to have a gynecologist examine it or perform a biopsy for confirmation.
The effects of emergency contraception on menstruation can vary; it may cause your period to come early or late.
Additionally, its contraceptive effectiveness is not 100%, with a failure rate of about 3%.
If your period is more than a week late, it is recommended to check for pregnancy.
Thank you! Wishing you peace and health, Dr.
Zhang.

When it comes to understanding vaginal bumps and menstrual delays after taking emergency contraception, it's important to consider several factors that could contribute to these symptoms.
Firstly, the appearance of a round, raised bump near the vaginal opening could be indicative of several conditions. While you mentioned the possibility of it being genital warts (caused by the human papillomavirus, HPV), there are other potential explanations as well. For instance, it could be a benign cyst, such as a Bartholin's gland cyst, which can occur when the gland becomes blocked. Other possibilities include follicular cysts, sebaceous cysts, or even a small abscess. If the bump is painless and does not change in size or appearance, it may not be a cause for immediate concern. However, if it becomes painful, changes in appearance, or is accompanied by other symptoms such as itching or discharge, it is advisable to consult a healthcare provider for a proper diagnosis.

Regarding the menstrual delay after taking emergency contraception, it is not uncommon for hormonal contraceptives, including emergency contraceptive pills (ECPs), to cause changes in your menstrual cycle. ECPs can lead to a delay in menstruation, as they work by altering the hormonal balance in your body to prevent ovulation. This hormonal disruption can result in your period being delayed by several days or even weeks. In your case, a one-month delay is on the longer side but can still be within the range of normal reactions to emergency contraception.
It's also worth noting that stress, changes in weight, and other health factors can influence your menstrual cycle. Since you mentioned that you took the emergency contraception and used condoms during intercourse, the likelihood of pregnancy is low, especially since you have taken a pregnancy test that returned negative. However, if your period does not arrive soon, or if you have any concerns about your health, it would be prudent to follow up with your healthcare provider. They can perform a thorough evaluation and may suggest further testing if necessary.

In summary, while the bump you noticed could be benign, it is essential to monitor it and seek medical advice if it changes or causes discomfort. As for the menstrual delay, it is likely a result of the emergency contraception, but if it persists, consulting a healthcare professional is the best course of action to ensure your overall reproductive health is maintained.
