Pregnancy Symptoms and Chances: A Guide for Couples

Probability of pregnancy and other symptoms?

Hello Doctor, my girlfriend's last menstrual period started on July 1.
Before her period on July 1, we had unprotected intercourse, and shortly after, her period began with a heavy flow.
We had protected intercourse on July 7, July 14, and July 18, and I checked the condoms afterward, and there were no tears.
After our encounter on July 18, I cleaned my penis and urinated before taking a warm bath with my girlfriend.

Yesterday (July 23), my girlfriend mentioned she felt a slight dull pain in her lower abdomen and discomfort in her breasts, including itchy nipples.
However, today the dull pain in her abdomen has significantly decreased, leaving only the itchy nipples, and the breast discomfort has also become less noticeable.
Yesterday, my girlfriend went to bed early and slept for a long time, which should count as sufficient sleep.
However, she told me half an hour after waking up that she really wanted to sleep again.
I saw that early pregnancy symptoms include drowsiness, which makes me a bit worried.

Could this be a sign of pregnancy? My girlfriend has had irregular menstrual cycles in the past, with her most recent cycle being 30 days.
However, she rarely experienced breast tenderness before her period in the past.
I'm unsure if the reduction in symptoms is due to her getting enough sleep, and I don't know what the likelihood of pregnancy is.
Thank you, Doctor, for your response.

Hello, the failure rate of using condoms for contraception is over 5%, which makes it less reliable compared to other methods.
Additionally, early pregnancy may not present specific symptoms, and subjective symptoms cannot be used to make a judgment.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

Understanding pregnancy symptoms and the chances of conception can be quite complex, especially for couples who are navigating the early stages of pregnancy. Based on the timeline and symptoms you've described, let's break down the situation to provide clarity.

First, it's important to note that your girlfriend's menstrual cycle is a critical factor in determining the likelihood of pregnancy. You mentioned that her last period started on July 1st, and she experienced heavy bleeding, which is a strong indicator that she was not pregnant at that time. The timing of ovulation typically occurs about 14 days before the next expected period, which would place it around mid-July for a 30-day cycle. Since you had unprotected intercourse just before her period, it is highly unlikely that she conceived from that encounter.

The subsequent sexual encounters you had on July 7th, 14th, and 18th were protected with condoms, and you confirmed that there were no breakages. This further reduces the chances of pregnancy, as condoms are effective in preventing sperm from reaching the egg when used correctly.

Now, regarding the symptoms your girlfriend is experiencing—mild lower abdominal discomfort, breast tenderness, and itchy nipples—these can be associated with various factors, including hormonal changes, premenstrual syndrome (PMS), or even stress. The fact that her symptoms have fluctuated, with the abdominal discomfort decreasing and breast tenderness becoming less pronounced, suggests that these may not be definitive signs of pregnancy.
In early pregnancy, common symptoms can include fatigue, breast tenderness, nausea, and increased urination. However, many of these symptoms can also be attributed to other conditions or hormonal fluctuations unrelated to pregnancy. For instance, the changes in breast sensitivity can occur due to hormonal shifts in the menstrual cycle, especially if her cycles have been irregular in the past.

The mention of increased sleepiness can also be a result of various factors, including lifestyle changes, stress, or even the body's response to hormonal changes. If your girlfriend has been feeling more tired than usual, it could be due to a combination of physical and emotional factors, rather than a clear indication of pregnancy.

Given that your girlfriend's menstrual cycle has been irregular, it might be beneficial for her to track her cycle more closely moving forward. If her period does not arrive as expected, or if she continues to experience symptoms that concern her, it would be wise for her to take a home pregnancy test for confirmation. These tests are most accurate when taken after a missed period.

In conclusion, while there are some symptoms that could suggest pregnancy, the timing of your sexual encounters and the use of protection significantly lower the likelihood of conception. If your girlfriend remains concerned about her symptoms or if her period does not arrive, consulting with a healthcare provider would be the best course of action. They can provide further evaluation and guidance based on her individual health and circumstances.
