Probability of Pregnancy


Hello, Doctor.
My menstrual cycle is 34 days, and my period lasts for 6 days.
My last menstruation was from October 16 to October 21.
I had unprotected external ejaculation on October 22, November 11, and November 13.
I would like to know if these dates fall within my safe period.
I am expecting my period on November 17, but it has not arrived yet.
I am only experiencing symptoms like leg swelling and hunger.
Currently, my discharge is of a type that breaks easily and is not sticky.
Could you please advise if this indicates pregnancy?

More Info


Understanding the chances of pregnancy and the concept of safe and dangerous periods is crucial for anyone who is sexually active and not planning to conceive. Based on the information provided, let's break down the key elements regarding your menstrual cycle, the timing of sexual intercourse, and the symptoms you are experiencing.


Menstrual Cycle and Ovulation
Your menstrual cycle is 34 days long, with a period lasting 6 days. Ovulation typically occurs about 14 days before the start of your next period. In your case, if your last menstrual period started on October 16, you would expect your next period around November 19. This means your ovulation would likely occur around November 2.
The "dangerous period," or the time when you are most likely to conceive, is generally considered to be the 5 days leading up to ovulation and the day of ovulation itself. Therefore, for a cycle of 34 days, your dangerous period would be approximately from October 28 to November 3.

Timing of Intercourse
You mentioned having unprotected external ejaculation on October 22, November 11, and November 13. The first date (October 22) falls outside your dangerous period, while the latter two dates (November 11 and 13) are after your ovulation window. Therefore, the chances of pregnancy from those encounters are lower, especially since external ejaculation reduces the likelihood of sperm entering the vagina.


Symptoms and Signs of Pregnancy
You noted that your period was expected on November 17 but has not yet arrived. The symptoms you are experiencing—such as leg swelling and increased hunger—are not definitive indicators of pregnancy. The type of discharge you described, which is not sticky or stretchy, also does not strongly suggest ovulation or pregnancy.

Pregnancy Testing
If your period does not arrive within a week of its expected date, it would be advisable to take a home pregnancy test for confirmation. These tests are generally accurate when taken after a missed period. If the test is positive, or if you continue to have symptoms that concern you, consulting a healthcare provider would be the next step.


Safe Practices and Contraception
Given your concerns about unprotected sex and the potential for pregnancy, it is important to consider reliable contraception methods if you are not planning to conceive. Options include hormonal birth control (pills, patches, injections), intrauterine devices (IUDs), and barrier methods like condoms. Each method has its own effectiveness and side effects, so discussing these options with a healthcare provider can help you choose the best one for your situation.


Conclusion
In summary, based on your menstrual cycle and the timing of your sexual encounters, the likelihood of pregnancy appears low. However, if your period does not arrive soon, taking a pregnancy test is recommended. Additionally, if you have concerns about potential pregnancy or the need for contraception, seeking advice from a healthcare professional can provide you with the necessary support and information. Remember, understanding your body and menstrual cycle is key to managing your reproductive health effectively.
