Am I Pregnant? Menstrual Irregularities and Contraception - Obstetrics and Gynecology

Will I get pregnant this way?


Hello Doctor: I had my menstrual period twice this month—once on June 8 and again on June 21.
Why did I have two periods? This month, I had unprotected intercourse with my boyfriend on July 3, 4, and 6, with ejaculation inside.
Is there a chance I could be pregnant? Later, I thought about getting a menstrual induction injection...
After receiving the injection, I had unprotected intercourse again on the same day and the following day.
Is there a high chance of pregnancy? >.< || The gynecologist prescribed me these medications (KM tab.
and MORESAFE tab.).
What kind of medications are these? What effects could they have on my body? Please help me with these questions.
Thank you! ^^

Hello: If you do not want to become pregnant, the best method is to practice effective contraception, as there is always a possibility of pregnancy whenever sexual intercourse occurs.

More Info


Understanding whether you are pregnant can be a complex issue, especially when dealing with menstrual irregularities and the use of contraception. Based on your description, you experienced two menstrual periods in June, which can be indicative of several factors, including stress, hormonal imbalances, or other underlying health issues. It's not uncommon for women to experience irregular cycles, especially if there have been changes in lifestyle, stress levels, or health.

You mentioned having unprotected intercourse on multiple occasions in July, particularly around the time of your menstrual irregularities. If you had your last period on June 21 and had unprotected sex shortly after, there is a possibility of pregnancy, especially if you ovulated during that time. Sperm can survive in the female reproductive tract for up to five days, so if you ovulated shortly after your last period, conception could occur.

Regarding the medications you mentioned—KM tab and MORESAFE tab—these are likely related to menstrual regulation and emergency contraception. KM tab is often used to induce menstruation, while MORESAFE is an emergency contraceptive pill. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but it can work up to five days after. However, it is not 100% effective, and its efficacy can be influenced by where you are in your menstrual cycle.

If you took these medications and then had unprotected intercourse again, it is important to understand that while the emergency contraceptive can reduce the chances of pregnancy, it does not guarantee that you will not conceive. If you are concerned about the possibility of being pregnant, the best course of action is to take a home pregnancy test after a missed period or consult with a healthcare provider for a blood test, which can provide more definitive results.

In terms of your health, it is essential to monitor any side effects from the medications you have taken. Common side effects of emergency contraceptives can include nausea, fatigue, headache, and changes in your menstrual cycle. If you experience severe side effects or have concerns about your health, it is crucial to seek medical advice.

In conclusion, if you suspect you might be pregnant, taking a pregnancy test is the most straightforward way to confirm your status. If you continue to experience irregular periods or have concerns about your reproductive health, consulting with a gynecologist or healthcare provider is advisable. They can provide personalized advice and support based on your specific situation. Remember that understanding your body and menstrual cycle is vital for reproductive health, and seeking professional guidance can help clarify any uncertainties you may have.
