Menstrual Delay: Concerns After Taking Menstrual Regulation Pills

Menstrual delay medication

Can I ask a question? My menstrual cycle is usually very regular, always starting at the end of the month.
However, I originally had my period from January 23 to 26, but I took medication to delay my period for two weeks, and then I got it on February 7.
I had sexual intercourse on February 29, and I was supposed to have my period from March 7 to 10, but it still hasn't arrived.
I'm really worried about the possibility of being pregnant from the encounter on February 29.
Also, does taking that kind of medication for too long affect my body in an abnormal way? Please respond quickly; I'm very anxious.

EEEEEEEEEEEE, 10~19 year old female. Ask Date: 2004/03/14

Dr. Liang Yinpan reply Obstetrics and Gynecology

Ms.
EE, you have taken medication to prolong your menstrual period, which has interfered with your ovarian ovulation cycle, resulting in irregular menstruation.
Therefore, it is uncertain whether the sexual activity on February 29th could lead to pregnancy.
If your period has not yet arrived, please take a pregnancy test as soon as possible to determine if you are pregnant.
Wishing you good luck, and please take appropriate contraceptive measures just in case.
Sincerely, Liang Yinpan 930317

More Info

Understanding menstrual delays can be quite concerning, especially after taking menstrual regulation pills. It’s important to clarify a few points regarding your situation.

Firstly, menstrual regulation pills, often referred to as emergency contraceptive pills (ECPs), are designed to prevent pregnancy after unprotected intercourse. They can also affect your menstrual cycle, leading to delays or irregularities. The hormones in these pills can disrupt your normal hormonal balance, which may cause your period to come later than expected. In your case, since you took the pills two weeks prior to your expected period, it is possible that the hormonal changes induced by the medication are the reason for your delayed menstruation.

Regarding your concern about the sexual encounter on February 29, if you had unprotected intercourse during your fertile window, there is a possibility of pregnancy. The fertile window typically occurs around the time of ovulation, which is usually about 14 days before your next expected period. If your cycle is regular and you were expecting your period around March 7-10, then February 29 could fall within that window. However, since you took the menstrual regulation pills, they may have altered your ovulation timing, making it difficult to predict your fertility accurately.

If your period does not arrive within a week or so of its expected date, it would be advisable to take a home pregnancy test. These tests are generally reliable and can help you determine if you are pregnant. If the test is positive, you should consult a healthcare provider for further guidance.

As for the concern about taking menstrual regulation pills for an extended period, it is generally not recommended to use these pills as a regular form of contraception. Frequent use can lead to hormonal imbalances and may cause side effects such as irregular periods, nausea, fatigue, and headaches. If you find yourself needing to use these pills often, it may be beneficial to discuss more reliable and regular forms of contraception with a healthcare provider.

In summary, your menstrual delay could be a result of the hormonal changes from the menstrual regulation pills. If your period does not arrive soon, consider taking a pregnancy test. For future contraceptive needs, consulting with a healthcare provider for a more consistent method may be the best course of action. Remember, it’s always important to prioritize your reproductive health and seek professional advice when in doubt.
