Menstrual and pregnancy issues?


I'm not a doctor, but I can provide some general information.
If your girlfriend's menstrual cycle is 35 days and her last period was from October 2 to October 8, she would likely ovulate around October 22.
Since you engaged in intimate contact on October 12, it would be before her ovulation window, which generally reduces the likelihood of pregnancy.

However, if there was any semen on your hands and it came into contact with her vaginal area, there is a very small risk of pregnancy, although it is quite low.
The symptoms you mentioned, such as mild abdominal pain and normal discharge, could be related to her menstrual cycle or ovulation rather than pregnancy.

If her period is due on November 5 and she experiences any unusual symptoms or a missed period, it would be advisable for her to take a pregnancy test for confirmation.
It's always best to consult with a healthcare professional for personalized advice and guidance.

Dr. Huang Jianzhong reply Obstetrics and Gynecology


Your girlfriend had her period from October 2 to October 8, and her cycle is 35 days long.
If you engaged in foreplay on October 12 and had some fluid from masturbation on your hands (without ejaculation) before touching her (with minimal penetration, as she is a virgin), is there a chance of pregnancy? Answer: There is no chance of pregnancy.
As of now, your girlfriend's body shows no abnormalities.
However, her period is due on November 5, and she experienced a brief sharp pain in her abdomen on November 2.
Is this normal? Answer: It is relatively normal, and her discharge is consistent with previous cycles, with only an increase during ovulation (she also reports sharp pain during ovulation).
Is there a possibility of pregnancy, or are we just overthinking it? Answer: You are likely overthinking it.

Understanding menstrual cycles and the potential for pregnancy can be a source of anxiety for many couples. In your case, let's break down the situation based on the information provided.

Your girlfriend's menstrual cycle is 35 days long, which is longer than the average cycle of 28 days. This means that ovulation, which typically occurs about 14 days before the start of the next period, would likely happen around day 21 of her cycle. Given that her last period started on October 2 and lasted until October 8, ovulation would likely occur around October 22.
On October 12, you engaged in sexual activity with your girlfriend, which was primarily external and did not involve ejaculation. The concern here is whether pre-ejaculate fluid (pre-cum) could lead to pregnancy. Pre-ejaculate can contain sperm, but the likelihood of pregnancy from such contact is relatively low, especially if there was no direct ejaculation and penetration was minimal. However, it is important to note that while the risk is low, it is not zero.

Regarding the abdominal pain your girlfriend experienced on November 2, this could be related to a variety of factors. It could be a normal part of her menstrual cycle, such as ovulation pain (also known as mittelschmerz), or it could be related to other physiological changes. Since her period is expected on November 5, the timing of this discomfort could align with her body's preparation for menstruation.

As for the possibility of pregnancy, if your girlfriend's menstrual cycle is regular and she has not missed her period, it is less likely that she is pregnant. The symptoms you describe, such as the normal amount of discharge and the timing of the abdominal pain, suggest that her body is functioning as expected within her cycle.
If she does miss her period or experiences any unusual symptoms, it would be advisable for her to take a home pregnancy test or consult a healthcare provider for further evaluation. Stress and anxiety about potential pregnancy can also lead to physical symptoms, so it's important to approach this situation with a calm mindset.

In summary, while there is a slight risk of pregnancy from the activities you described, the likelihood is low given the timing and nature of the contact. If your girlfriend's period arrives as expected, it is a strong indication that she is not pregnant. If there are any concerns or changes in her health, seeking advice from a healthcare professional is always a good step.
