Pregnancy Concerns: Irregular Periods and Safe Practices

Are you pregnant?

Hello, doctor: My boyfriend and I are engaging in anal intercourse to avoid pregnancy.
Since the summer, my menstrual cycle has been irregular.
I got my period on November 24, 2017, and it lasted for over ten days without pain.
In early December, I couldn't tolerate it any longer and went to see a gynecologist.
I was prescribed hemostatic and analgesic medications, which resolved the issue.
The doctor mentioned that it might have been caused by stress (as I had exams around that time) and that my next period would come as usual.
However, my normal cycle is usually at the end of the month, and it suddenly came on the 23rd, so I have been monitoring both.
I was waiting for my period on December 24, but it didn't come.
I then waited until December 28, and still no period.
Now it's January 2, 2018, and I still haven't gotten it.

Questions:
1.
Could the hemostatic and analgesic medications I took last time cause a delay in my period this time?
2.
Is it possible that my period hasn't come yet because I had such a long flow last time that I ran out of menstrual blood?
3.
After anal intercourse, my boyfriend always ejaculates in my mouth.
He wipes his hands with tissue afterward and lets me check and clean his fingers before he inserts them into my vagina.
Does this mean the chance of pregnancy is nearly zero?
4.
Should I be concerned about the possibility of pregnancy given my current situation?

Hello, the factors that can affect the menstrual cycle or cause intermenstrual bleeding are numerous, including age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraception, diet, polycystic ovary syndrome, uterine or cervical lesions, infections, ovulation, and pregnancy, among others.
Given your situation, there is still a possibility of pregnancy, and it is important to prevent other sexually transmitted infections.
I recommend that you consult a gynecologist to determine whether the cause is hormonal imbalance or something else.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info

When it comes to pregnancy concerns, particularly regarding irregular periods and safe practices, there are several factors to consider. Let's break down your questions and provide a comprehensive understanding of the situation.

1. Impact of Medications on Menstrual Cycle: It is possible that the medications you took, such as hemostatic and analgesic drugs, could influence your menstrual cycle. Stress is also a significant factor that can lead to irregular periods. The body responds to stress by altering hormone levels, which can delay ovulation and, consequently, menstruation. If your menstrual cycle was already irregular, the combination of stress and medication could further complicate its regularity.

2. Possibility of Menstrual Flow Ending: If your last period was unusually prolonged, it is unlikely that it would completely deplete your menstrual flow. However, hormonal fluctuations can lead to lighter periods or missed cycles. It’s essential to monitor your body’s signals and consult a healthcare provider if you experience significant changes.

3. Pregnancy Risk from Anal Intercourse: Engaging in anal intercourse followed by manual stimulation of the vagina does carry a minimal risk of pregnancy, primarily if semen comes into contact with the vaginal area. While the likelihood is low, it is not zero. Sperm can survive outside the body for a short time, and if there is any transfer of sperm from the anus to the vagina, there is a potential risk of pregnancy. However, if your boyfriend did not ejaculate near the vaginal opening, the risk remains very low.

4. Concerns About Pregnancy: Given your situation, it is understandable to have concerns about pregnancy. If you have missed your period for an extended time, it would be prudent to take a home pregnancy test for reassurance. These tests are generally accurate and can provide clarity on your situation. If the test is negative and your period still does not arrive, consider consulting a healthcare provider to explore other potential causes for your irregular cycle.

In summary, irregular periods can stem from various factors, including stress, hormonal changes, and medications. While the risk of pregnancy from your described activities is low, it is not entirely absent. If you are concerned about pregnancy or your menstrual health, it is always best to consult with a healthcare professional who can provide personalized advice and support. Regular check-ups and open communication with your healthcare provider can help you navigate these concerns effectively.
