Hi,
Bleeding between periods after non-penetrative sexual activity can have several potential causes, including
hormonal imbalances, vaginal infections, or trauma to the
cervix or vaginal walls. However, it is unlikely that the bleeding is related to the non-penetrative sexual activity you described.
If your girlfriend was already on her period during the time of the sexual activity and the bleeding is light and dark brown, it may be old blood from the
uterus is expelled. However, if the bleeding continues or becomes heavier, it would be best for your girlfriend to schedule an appointment with her healthcare provider to determine the cause.
Regarding
pregnancy, it is important to note that pregnancy can only occur if sperm enters the vagina and fertilizes an egg. In the situation you described, it is unlikely that your girlfriend is pregnant. However, if she is concerned about pregnancy, she can take a pregnancy test to confirm or rule out the possibility.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
