Ovulation and Pregnancy Risks After Unprotected Sex

Is pregnancy possible?

Hello Doctor, my last menstrual period ended on December 22.
Four days later, on December 26, I had sexual intercourse while using a condom and there was no ejaculation inside.
However, I have been experiencing pain in my right lower abdomen, near the ovarian area.
In previous medical visits, doctors assessed it as ovulation pain, but I am confused about whether ovulation could occur so soon, as I have heard that ovulation cycles vary for each person.
I am also wondering if this could be a psychological effect, as I am taking the antidepressant Lexapro and the sleep medication diazepam 2 mg.
I feel very anxious about sex, so I would like to ask the doctor about the possibility of pregnancy.

Additionally, my first sexual encounter occurred during a potentially fertile period, although I only penetrated briefly due to pain.
My menstrual period then arrived three days early, but on the first day, I experienced unusual abdominal pain with only blood clots, which led me to visit a gynecologist who requested a pregnancy test.
During the urine test, there was blood in my urine, and the pregnancy test result was negative.
However, the doctor mentioned that testing again in two weeks might not be accurate.
Although I had a complete menstrual cycle afterward (from December 16 to December 22), my anxiety has led me to question whether this was indeed my period and whether my next one will arrive smoothly.

The situation surrounding the sexual encounter has caused me significant anxiety, and I considered taking emergency contraception, but I have heard it can be harmful to the body and I am unsure if it would interact with my psychiatric medications.
I really want to confirm whether this situation is safe and if there is no risk of pregnancy.
I apologize for asking so many questions, and I appreciate your patience in reading this.
I hope to receive a correct and professional response from you to help stabilize my mental state.
Thank you!

Hello, based on your description, there is a possibility of pregnancy.
Since your menstrual cycle has been irregular recently, it is difficult to predict the timing of ovulation and menstruation this time.
I recommend that if you are unable to confirm whether the bleeding on the 12th to 16th is your period, you should consult a physician for an ultrasound and other relevant examinations two weeks later to determine if it is menstruation or if there is a pregnancy.
Thank you! However, pregnancy cannot be determined solely by subjective symptoms.
If your period does not arrive by the end of the month, it is advisable to take a urine test to check for pregnancy.
Thank you! Wishing you peace and health.

Understanding ovulation and the associated risks of pregnancy after unprotected sex is a common concern for many individuals. Based on your description, it seems you have a few key points to address regarding your menstrual cycle, ovulation, and the potential for pregnancy.

Firstly, it’s important to understand the menstrual cycle and ovulation. The average menstrual cycle lasts about 28 days, but it can vary significantly from person to person, ranging from 21 to 35 days. Ovulation typically occurs around the midpoint of the cycle, approximately 14 days before the start of your next period. However, this can vary based on individual factors such as stress, hormonal changes, and overall health.

In your case, you mentioned that your last menstrual period ended on December 22, and you had sexual intercourse on December 26. If your cycle is around 28 days, ovulation could potentially occur around December 6 to December 14. Since you had intercourse shortly after your period, it is less likely that you were in your fertile window, especially if you were using a condom and there was no ejaculation inside the vagina. Condoms are a reliable form of contraception when used correctly, and they significantly reduce the risk of pregnancy.

Regarding the pain you experienced in your right lower abdomen, which you suspect might be ovulation pain (mittelschmerz), it is indeed possible to feel discomfort around the time of ovulation. However, this pain can also be influenced by other factors, including anxiety and stress, especially if you are currently taking medications like Lexapro (an antidepressant) and Diazepam (an anti-anxiety medication). Anxiety can manifest physically, leading to sensations that may be interpreted as pain or discomfort.

You expressed concern about the possibility of pregnancy despite the use of a condom and the timing of your cycle. Given that you had a complete menstrual cycle following the sexual encounter and that your pregnancy tests returned negative, it is highly unlikely that you are pregnant. Pregnancy tests are most accurate when taken after a missed period, and since you had a regular menstrual cycle, it suggests that your body is functioning normally.

As for your concerns about taking emergency contraception (the "morning-after pill"), it is generally safe to use, but it is advisable to consult with your healthcare provider, especially considering your current medications. Emergency contraception can be effective if taken within 72 hours after unprotected intercourse, but it is not intended for regular use and can cause temporary changes in your menstrual cycle.

In conclusion, based on the information provided, the risk of pregnancy appears to be low given the use of a condom and the timing of your cycle. However, if you continue to experience anxiety regarding your sexual health, it may be beneficial to discuss these feelings with a healthcare professional who can provide support and reassurance. Regular check-ups with your gynecologist can also help address any ongoing concerns about your menstrual cycle and reproductive health. Remember, open communication with your partner and healthcare provider is key to managing anxiety and ensuring your sexual health.
