Can I get pregnant?


My menstrual cycle has always been regular, and I have had safe sexual practices.
My periods usually last 6-8 days, and this time it started on November 30.
On December 2, I had unprotected intercourse with my boyfriend, but he felt it was inappropriate and quickly withdrew without ejaculating.
On December 4, we tried again, but after he felt aroused, he also quickly withdrew and ejaculated on my thigh.
As of today, I still have a little bit of menstrual bleeding (it's almost over).
However, the first unprotected encounter occurred during my period, and although it was brief, I still experienced mild abdominal and lower back pain, which is typical during menstruation.
We cleaned up immediately before and after.
Besides worrying about the possibility of pregnancy, I am also concerned about the risk of infection, as I currently have slight itching in the vulvar area.
Should I wait 12 days to take a pregnancy test?

Hello, the chances of pregnancy are low.
Generally, a pregnancy test should be taken at least 12 days after conception to yield accurate results.
It is always best to use preventive measures beforehand and not to rely on the safe period.
If your period is more than a week late, it is advisable to consult a gynecologist.
Wishing you good health.

Based on your description, it seems you are concerned about the possibility of pregnancy after engaging in unprotected intercourse during your menstrual cycle. Let's break down your situation and address your concerns regarding pregnancy risk and potential infections.

Firstly, it’s important to understand that the likelihood of becoming pregnant during your menstrual period is generally low, but not impossible. Sperm can survive in the female reproductive tract for up to five days, and if you have a shorter menstrual cycle (for example, 21-24 days), ovulation could occur soon after your period ends. In your case, since you mentioned that your menstrual cycle is usually regular, the risk of pregnancy from intercourse on December 2nd, while you were still menstruating, is relatively low. However, the risk is not zero, especially since you had unprotected intercourse again on December 4th.

Regarding the timing of your menstrual cycle, if your period started on November 30th and lasted for about 6-8 days, you would likely be nearing the end of your cycle when you had intercourse. The fact that you are still experiencing some menstrual bleeding could indicate that your period is concluding, which further reduces the likelihood of pregnancy. However, if you are experiencing symptoms such as abdominal pain or discomfort, it may be worth considering other factors, including hormonal fluctuations or potential ovulation.

As for the concern about infections, the mild itching you are experiencing could be a sign of a yeast infection or bacterial vaginosis, especially if you have recently engaged in sexual activity. It is essential to monitor these symptoms closely. If the itching persists or worsens, or if you develop additional symptoms such as unusual discharge or a strong odor, it would be advisable to consult a healthcare provider for an evaluation.

Regarding the timing of a pregnancy test, it is generally recommended to wait at least one week after a missed period for the most accurate results. Since you are still experiencing some bleeding, it may be prudent to wait about 12 days from the last unprotected intercourse (December 4th) before taking a home pregnancy test. This timing allows for the hormone hCG (human chorionic gonadotropin), which is produced during pregnancy, to reach detectable levels in your urine if you are indeed pregnant.

In summary, while the risk of pregnancy from the described encounters is low, it is not entirely absent. Monitoring your symptoms and waiting for the appropriate time to take a pregnancy test will provide you with clearer answers. If you have ongoing concerns about potential infections or pregnancy, seeking advice from a healthcare professional is always a good step to ensure your health and peace of mind.
