No bleeding after using emergency contraception following a medical abortion?


Q: I did not experience bleeding after taking the emergency contraceptive pill.
Hello, I used medication for a medical abortion on September 1, and I started bleeding on the morning of September 3.
I went to the clinic for an ultrasound at noon, and the doctor confirmed that the gestational sac had been expelled.
I returned to the clinic on September 8, and there was no more bleeding.
On September 14, I had sexual intercourse, and out of fear of becoming pregnant again, I took the emergency contraceptive pill within one hour.
However, it has been a week since taking the medication, and I have not experienced any bleeding.
I would like to know how effective this method of contraception is.
During my last sexual encounter, I took the emergency contraceptive pill within 24 hours, but two weeks later, my period did not arrive, and I tested positive for pregnancy! My first child was born in April.

Ms.
Chen: Hello, the contraceptive effect of emergency contraceptive pills is not 100%, and it does not guarantee bleeding afterward.
If a miscarriage occurred on September 3, the next menstrual period should arrive in 4 to 6 weeks.
Please pay attention to your menstrual cycle.

After an abortion, it is common for individuals to experience various symptoms, including bleeding and cramping. The situation you described involves a series of events following a medical abortion, including the use of medication, follow-up visits, and concerns about bleeding patterns and contraceptive use.
Firstly, it is important to understand that after a medical abortion, the body goes through a recovery process. This can include bleeding that may last for several days to weeks, and it is not unusual for the bleeding to vary in color and consistency. Fresh red blood may indicate active bleeding, while dark brown or black blood can be older blood that is being expelled from the uterus. The presence of blood clots can also be a normal part of this process, especially if the uterus is expelling tissue.

In your case, the bleeding you experienced after the abortion and the subsequent cramping could be attributed to several factors. These include:
1. Incomplete Abortion: Sometimes, not all of the pregnancy tissue is expelled from the uterus, which can lead to ongoing bleeding and cramping. This may require further medical intervention, such as a follow-up procedure to ensure the uterus is clear.

2. Uterine Contractions: Medications like Ergometrine, which are often prescribed post-abortion, are intended to help the uterus contract and expel any remaining tissue. While effective, these contractions can cause cramping and discomfort.

3. Hormonal Changes: After an abortion, the body undergoes significant hormonal changes as it returns to its pre-pregnancy state. This can affect menstrual cycles and may lead to irregular bleeding patterns.

Regarding your concern about the emergency contraceptive pill (ECP) taken after unprotected intercourse, it is important to note that ECPs are most effective when taken as soon as possible after unprotected sex, ideally within 72 hours. However, they can still be effective up to 120 hours after intercourse, although the efficacy decreases over time.
The absence of bleeding after taking the ECP does not necessarily indicate that it has failed. Some individuals may experience a delay in their menstrual cycle after taking ECPs, and it is not uncommon for the next period to be lighter or heavier than usual. If you have taken the ECP and are concerned about the possibility of pregnancy, it is advisable to take a home pregnancy test if your period does not arrive within a week of when it is expected.

In summary, your experience of bleeding and cramping post-abortion is not uncommon and can be attributed to various physiological factors. If you continue to experience unusual symptoms or have concerns about your menstrual cycle or potential pregnancy, it is crucial to consult with your healthcare provider for personalized advice and management. Regular follow-ups after an abortion are essential to ensure that the body is healing properly and to address any complications that may arise.
