Menstrual Cramps After Intercourse: Is It Normal?

Experiencing abdominal pain after having intercourse during menstruation?

I would like to ask the doctor, on the third day of my menstrual period, I had intercourse with my boyfriend, thinking that I wouldn't get pregnant during my period, so I didn't take any contraceptive measures.
Initially, my flow was very light, almost nonexistent, but after having intercourse, the flow increased two to three times, and I've been experiencing abdominal pain for two days.
The intercourse felt normal and was the same as usual.
Can you explain why this is happening? Is it not advisable to have intercourse during my period, or is there something wrong with my body?

Hello, the situation you are experiencing requires consideration of two important points.
First, vaginal bleeding does not necessarily indicate menstruation, especially when there is a hormonal imbalance, which can make it difficult to determine the cause.
There may also be other reasons for the bleeding, such as polyps, ectropion, or inflammation.
Second, post-coital bleeding can have many causes (hormonal imbalance, abrasions, inflammation, erosion, etc.), and a thorough examination is necessary to confirm the cause.
I recommend that if the bleeding persists or if you frequently experience this symptom, you should consult a gynecologist for evaluation and examination.
Additionally, it is not advisable to rely on the calendar method for contraception, as women with irregular bleeding may have a failure rate of over 50% using this method.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info

Experiencing menstrual cramps after intercourse can be a common occurrence, and there are several factors that may contribute to this situation. First, it's important to understand that during menstruation, the uterus is shedding its lining, and this process can lead to increased sensitivity and cramping. Engaging in sexual activity during this time can sometimes exacerbate these sensations due to the physical stimulation of the uterus and surrounding tissues.

When you mentioned that your menstrual flow increased significantly after intercourse, this can also be attributed to several physiological responses. Sexual arousal and orgasm can lead to increased blood flow to the pelvic area, which may result in a heavier menstrual flow. Additionally, the contractions of the uterus during orgasm can help expel menstrual blood, leading to a temporary increase in flow. This is generally not a cause for concern, as it is a normal physiological response.

Regarding the abdominal pain you are experiencing, it is not uncommon for individuals to feel increased cramping during their menstrual period, especially after sexual activity. The contractions of the uterus during menstruation can be intensified by physical activity, including intercourse. If the pain is mild and manageable, it is likely a normal response to the combination of menstruation and sexual activity. However, if the pain becomes severe, persistent, or is accompanied by other concerning symptoms such as heavy bleeding, fever, or unusual discharge, it would be advisable to consult a healthcare professional.

It is also worth noting that having intercourse during menstruation is generally safe and does not pose a risk of pregnancy, as you correctly pointed out. However, it is important to consider that while the likelihood of conception is low, it is not entirely impossible, especially if your menstrual cycle is irregular. If you are concerned about pregnancy or sexually transmitted infections (STIs), using protection is always a good practice, regardless of the timing within your menstrual cycle.

In summary, experiencing increased menstrual flow and cramps after intercourse during your period can be a normal response due to the physiological changes occurring in your body. If the symptoms you are experiencing are mild and manageable, it is likely nothing to worry about. However, if you have any concerns or if your symptoms worsen, it is always best to seek medical advice for a thorough evaluation and peace of mind. Remember, every individual's body is different, and what is normal for one person may not be for another. Listening to your body and seeking help when needed is key to maintaining your reproductive health.
