I had sexual intercourse on September 26 and 27, and took emergency contraception on September 28.
My period came on October 8, and I had intercourse on October 10 and 11, followed by taking emergency contraception on October 12.
My period started again on November 4, and I had intercourse on November 14 and 15, then took emergency contraception on November 16.
I experienced bleeding on November 23 that lasted about four days.
I had intercourse on November 30 but did not take emergency contraception due to abnormal bleeding.
On November 30, after intercourse, I did not take emergency contraception.
I visited a gynecologist on December 3 and was confirmed not pregnant.
On December 23, I bought a pregnancy test and it was negative.
I visited the gynecologist again on December 26, and the test was also negative.
As of January 4, my period has still not arrived.
Could I be pregnant?

Emergency contraception is intended as a last resort for preventing pregnancy and should not be used as a regular contraceptive method.
When used correctly, it is effective in preventing pregnancy, but it may affect subsequent menstrual cycles.
After consulting with a gynecologist to confirm that there is no pregnancy, medication can be administered to induce withdrawal bleeding (commonly referred to as a "menstrual period") in a non-pregnant uterus, ensuring that pregnancy has not occurred and alleviating any ongoing concerns.

Understanding irregular periods after contraceptive use can be quite complex, especially following events such as abortion and the use of emergency contraception. In your case, it seems you have experienced a series of menstrual irregularities after undergoing an abortion and subsequently using emergency contraception multiple times.
Firstly, it's important to recognize that hormonal fluctuations can significantly impact your menstrual cycle. After an abortion, your body undergoes various hormonal changes as it returns to its pre-pregnancy state. This can lead to irregular periods, which is not uncommon. The use of emergency contraception (like Plan B or similar pills) can also contribute to cycle irregularities. These medications contain hormones that can disrupt your normal hormonal balance, leading to changes in your menstrual cycle, including delayed periods, spotting, or even missed periods.

From your timeline, it appears that you have had several instances of unprotected intercourse followed by the use of emergency contraception. Each time you take these pills, they can alter your cycle. The fact that you experienced bleeding on November 23, which lasted about four days, could be a side effect of the emergency contraception rather than a regular menstrual period.
As for your current situation, where you have not had your period by January 4, it is essential to consider a few possibilities:
1. Hormonal Imbalance: The combination of recent abortion, emergency contraception, and the natural hormonal fluctuations can lead to a delay in your menstrual cycle. It may take some time for your body to regulate itself.

2. Pregnancy: Although you have taken multiple pregnancy tests that have returned negative results, it is still possible to have a false negative, especially if the test is taken too early. If you suspect pregnancy, it might be worth waiting a few days and testing again or consulting with your healthcare provider for a blood test, which is more sensitive than home urine tests.

3. Stress and Lifestyle Factors: Stress, changes in weight, and other lifestyle factors can also affect your menstrual cycle. If you have been under stress or have experienced significant changes in your life, this could contribute to your irregular periods.

4. Underlying Health Conditions: Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can also lead to irregular periods. If your cycle does not normalize soon, it may be worth discussing these possibilities with your healthcare provider.

In summary, while it is possible that your missed period could be due to pregnancy, it is also likely a result of hormonal changes from the abortion and the use of emergency contraception. If your period does not return in the next few weeks, or if you experience any concerning symptoms (such as severe pain or unusual discharge), it is advisable to seek medical attention. Your healthcare provider can offer guidance, perform necessary tests, and help you understand your reproductive health better.
