Can Abnormal Bleeding Affect Pregnancy Chances?

Is it possible to become pregnant from abnormal bleeding during intercourse?

My girlfriend usually has her menstrual cycle at the end of the month.
She suddenly experienced continuous bleeding starting from November 16 for a month.
She saw a doctor on December 19, who initially suggested the possibility of uterine polyps, but during the second examination, they could not be seen.
I would like to know if there is a high chance of pregnancy if we had unprotected intercourse on December 13 and 19.
Given the continuous bleeding, is it possible for her to ovulate?

Hello, it is important to use contraception at all times; otherwise, there is a chance of pregnancy.
Additionally, since your girlfriend's menstrual cycle is irregular, it is even more crucial to use contraceptive measures.
Wishing you both good health.

More Info

Abnormal bleeding during the menstrual cycle can indeed raise concerns regarding fertility and the chances of pregnancy. In your girlfriend's case, the prolonged bleeding that started on November 16 and continued for a month could be indicative of several underlying issues, including hormonal imbalances, uterine polyps, or other gynecological conditions.
Firstly, it is essential to understand that the menstrual cycle is regulated by hormones, and any disruption in this cycle can affect ovulation. If your girlfriend is experiencing continuous bleeding, it may indicate that her body is not functioning normally in terms of hormone regulation, which could potentially affect her ability to ovulate. Ovulation is crucial for conception, as it is the process where an egg is released from the ovary and can be fertilized by sperm. If she is not ovulating due to the abnormal bleeding, the chances of becoming pregnant would be significantly reduced.

Regarding the specific dates you mentioned, if she had unprotected intercourse on December 13 and 19, the likelihood of pregnancy would depend on whether she ovulated during that cycle. Typically, ovulation occurs about 14 days before the start of the next menstrual period. However, with the abnormal bleeding, it is challenging to determine when or if she ovulated. If the bleeding is due to anovulation (lack of ovulation), then the chances of pregnancy would be low.

Moreover, the presence of uterine polyps, which were mentioned in her medical evaluation, can also affect fertility. Polyps can interfere with the implantation of a fertilized egg or may cause hormonal imbalances that disrupt the menstrual cycle. If polyps are present, they may need to be addressed surgically to improve the chances of conception.

In terms of whether the bleeding could affect her chances of pregnancy, it is essential to consider the overall health of her reproductive system. Continuous bleeding can lead to anemia and other health issues, which may further complicate her ability to conceive. It is crucial for her to follow up with her healthcare provider for a thorough evaluation, which may include blood tests to check hormone levels, imaging studies to assess the uterus, and possibly a biopsy if there are concerns about the endometrial lining.

In conclusion, while it is possible to conceive during a cycle with abnormal bleeding, the chances may be significantly impacted by the underlying causes of the bleeding. It is advisable for your girlfriend to seek further medical evaluation to determine the cause of her bleeding and to discuss her fertility concerns. A healthcare provider can offer personalized advice and treatment options based on her specific situation, which is crucial for optimizing her chances of pregnancy in the future.
