What Happens After HCG Injection? Signs of Ovulation, Egg Release

Human Chorionic Gonadotropin (HCG) injection is commonly used in fertility treatments to trigger ovulation. If you're undergoing fertility treatments, you may be wondering what happens after the HCG injection and what signs to look for regarding ovulation, egg rupture, and early pregnancy.

How Does HCG Injection Work?

HCG injection is given to stimulate the final maturation of the egg and trigger ovulation. Typically, ovulation occurs within 24 to 36 hours after the injection, making it an essential step in fertility treatments such as intrauterine insemination (IUI) and in-vitro fertilization (IVF).

Symptoms of Ovulation After HCG Injection

After receiving the HCG injection, your body starts preparing for ovulation. Here are some common symptoms of ovulation after an HCG injection:

• Mild pelvic pain – You may experience slight discomfort or cramping as the follicle prepares to release the egg.
• Increase in cervical mucus – A clear, stretchy, and egg-white-like cervical mucus is a sign that ovulation is approaching.
• Higher basal body temperature – A slight rise in basal body temperature can indicate ovulation.
• Increased libido – Some women notice a boost in sexual desire due to hormonal changes.

Symptoms of Egg Rupture After HCG Injection

Egg rupture, also known as follicular rupture, occurs when the mature egg is released from the follicle, making it available for fertilization. Here are some common symptoms of egg rupture after an HCG injection:

• Sharp or mild pelvic pain – This pain, often referred to as mittelschmerz, occurs when the follicle releases the egg.
• Decrease in bloating – Some women feel a sudden relief from bloating after the follicle ruptures.
• Slight spotting – Light spotting or bleeding may occur due to follicle rupture.

Early Signs of Pregnancy After HCG Injection

If fertilization and implantation occur, you may start experiencing early signs of pregnancy after the HCG injection. These symptoms include:

• Mild cramping and implantation bleeding – Light spotting around 6-12 days after ovulation can be an early pregnancy sign.
• Fatigue and dizziness – Hormonal changes may cause tiredness and dizziness.
• Breast tenderness – Increased progesterone levels can make breasts feel sore or tender.
• Nausea and morning sickness – Some women experience nausea as an early sign of pregnancy.
• Frequent urination – Hormonal shifts may increase the urge to urinate.

When to Take a Pregnancy Test?

Since HCG is used as a trigger shot, it can stay in the system for about 10-14 days. Taking a pregnancy test too early may result in a false positive. It is recommended to take a test at least 14 days after the HCG injection for accurate results.

Conclusion

Understanding the symptoms of ovulation, egg rupture, and early pregnancy signs after an HCG injection can help you track your fertility journey. If you have concerns about your symptoms or pregnancy chances, consult your fertility specialist for guidance.
