How Long After a Menstrual Induction Shot Should I Expect My Period?

The menstrual induction injection was administered on July 11th?

Hello, I experienced a delay in my menstruation for a week, so I consulted a doctor.
The doctor recommended an injection to induce menstruation.
My menstrual cycle is usually quite regular, with a duration of 33 days.
I received the injection on July 11 at 3 PM, and as of now, July 14 in the evening, it has been 3 days without menstruation.
How many days after receiving the injection should I expect my period to start? If it exceeds a certain number of days without menstruation, when should I return to the hospital to see a doctor? Thank you.

Generally, it takes about 3 to 7 days.
Therefore, if there is no response by Monday, it is recommended to return for a follow-up on Tuesday.

More Info

After receiving a menstrual induction shot, it is common to wonder when you can expect your period to arrive. The timing can vary significantly from person to person, depending on various factors such as individual hormonal levels, the specific medication used, and your overall health. Generally, after receiving a menstrual induction shot, many women may expect their period to start within a few days to a week. However, it is not unusual for it to take longer, especially if your menstrual cycle is typically regular.

In your case, since you received the shot on July 11 and are now on July 14 without any signs of menstruation, it is still within the normal range of variability. Some women may experience their period as soon as 24 to 48 hours after the injection, while others may take up to a week or longer. The medication used for induction typically works by stimulating the lining of the uterus to shed, which can take some time to manifest as a period.

If your period does not arrive within a week of the injection, it is advisable to monitor your symptoms closely. If you experience any unusual symptoms such as severe abdominal pain, heavy bleeding, or any signs of an allergic reaction, you should seek medical attention immediately. Additionally, if your period has not started within two weeks of the injection, it would be prudent to contact your healthcare provider for further evaluation. They may want to check for any underlying issues that could be affecting your menstrual cycle, such as hormonal imbalances or other gynecological concerns.

It is also important to consider that stress, changes in weight, and other lifestyle factors can impact your menstrual cycle. If you have been under significant stress or have experienced any recent changes in your routine, these could also contribute to a delay in your period.

In summary, while it is common to expect your period to start within a few days to a week after a menstrual induction shot, individual experiences can vary. If you do not see your period within two weeks, or if you have any concerning symptoms, it is best to consult your healthcare provider for guidance and potential further investigation.
