What is one possible side effect of the Etonogestrel implant?

• A. Weight loss
• B. Vaginal bleeding
• C. Increased libido
• D. Decreased calcium absorption

Answer: (B)

The presence of vaginal bleeding is a well-documented side effect associated with the use of the Etonogestrel implant. This contraceptive method, which releases a form of progestin, can lead to changes in menstrual patterns for some users, including prolonged or irregular bleeding, and in some cases, amenorrhea (the absence of menstruation).

This occurs because the Etonogestrel implant works primarily by preventing ovulation, thickening cervical mucus, and thinning the endometrial lining, which can all affect the regularity and characteristics of menstrual bleeding. Many users report experiencing lighter periods or changes in their cycle length, but some may encounter unexpected or unpredictable bleeding patterns.

This variability in bleeding is important for patients to understand when choosing this method of contraception so they can manage any concerns that may arise from these side effects. Recognizing that bleeding changes can be a normal response to the implant can help with adherence and satisfaction with this contraceptive choice.
