Pregnancy Chances: Your Menstrual Cycle and Risks

Pregnancy Testing: Probability of Conception

Hello doctor, my menstrual cycle is not very regular; sometimes it comes early, sometimes on time, and sometimes I even miss a month.
I downloaded two period tracking apps, one predicts my period will start on May 16 and the other on May 19.
My last period was from April 14 to April 20, but I haven't gotten my period this month, which worries me because on May 19, I had some intimate contact with my boyfriend (without sexual intercourse).
I touched my boyfriend's genitals, but I did not feel any moisture (pre-ejaculate fluid).

1.
What is the likelihood of pregnancy in this situation?
2.
Assuming there was some secretion on my boyfriend's genitals when I touched him, if he then inserted his fingers into my vagina, is there a possibility of pregnancy?

More Info

Understanding your menstrual cycle and the associated risks of pregnancy is crucial, especially when there are irregularities in your cycle. Based on your description, it seems that your menstrual cycle is not consistent, which can complicate your understanding of ovulation and fertility.

1. Pregnancy Chances from Non-Penetrative Contact: The likelihood of becoming pregnant from non-penetrative sexual activities, such as touching or rubbing, is generally low. If there was no direct penetration and no visible transfer of seminal fluid (which includes sperm), the chances of pregnancy are minimal. However, it is important to note that sperm can be present in pre-ejaculatory fluid (pre-cum), which can sometimes be released during arousal. If your boyfriend had any sperm on his hands and then touched your vaginal area, there is a theoretical risk of pregnancy, albeit very low.

2. Menstrual Cycle and Ovulation: Understanding your menstrual cycle is key to assessing your pregnancy risk. A typical menstrual cycle lasts about 28 days, but cycles can range from 21 to 35 days. Ovulation usually occurs about 14 days before your next period is due. If your cycle is irregular, predicting ovulation becomes more challenging. If you had sexual contact around the time you were expected to ovulate, the risk of pregnancy increases. However, since you mentioned that your period is late, it may be worth considering a pregnancy test if your period does not arrive soon.

3. Irregular Menstrual Cycles: Irregular cycles can be caused by various factors, including stress, hormonal imbalances, weight changes, and underlying health conditions. If your cycles continue to be irregular, it may be beneficial to consult a healthcare provider. They can help identify any underlying issues and provide guidance on managing your menstrual health.

4. Pregnancy Testing: If your period is late, taking a home pregnancy test can provide clarity. These tests are most accurate when taken after a missed period. If the test is positive, it is advisable to schedule an appointment with a healthcare provider for further evaluation and prenatal care.

5. Preventive Measures: If you are concerned about unintended pregnancy, consider discussing contraceptive options with your healthcare provider. There are various methods available, including hormonal contraceptives, barrier methods, and long-acting reversible contraceptives (LARCs), which can help you manage your reproductive health effectively.

In summary, while the risk of pregnancy from the activities you described is low, it is essential to monitor your menstrual cycle and consider taking a pregnancy test if your period does not arrive. If you have ongoing concerns about your menstrual irregularities or pregnancy risks, consulting a healthcare professional can provide you with personalized advice and support.
