Patient's question:
On October 13th, my period arrived around that time, but I'm not very clear about the exact date. However, this time it was delayed by about 10 days. In August, my period was on the 29th, and it was always on time before, with no delay of more than three days. It ended around the 16th or 17th, I think. On the 23rd, I had another unwanted relationship with a colleague because I drank too much. He didn't come inside, but it was only that once. After the 24th, I only had sex with my boyfriend, and we did it many times. Today, on November 29th, I got a pelvic ultrasound, and the results showed that my uterus is anteverted and reduced in size. Inside the uterus, there was a 2.2×1.3 cm gestational sac with a yolk sac echo, embryonic union, and a heartbeat. However, when I had a pelvic ultrasound at the company health check on November 6th, nothing was detected. Can you estimate the timing of fertilization? Was it in November that I got pregnant? If it was in October, what date would that be? Could it be from my colleague? I'm so worried. I really want a baby with my boyfriend, but now I'm not sure. I'm so heartbroken and confused~Doctor's answer:
According to your time estimation, the 30th is approximately the ovulation period. The gestational sac is 2.2×1.3. It is preliminarily considered that it is about 45 days pregnant, about 30 days after intercourse, which means intercourse and delivery during the ovulation period. The time of intercourse with your colleague has a safe period, and the semen was not deposited internally. Additionally, considering the time of intercourse you mentioned, the baby is your boyfriend's, so there is no need to worry. Always maintain a relaxed mood, take folic acid orally, and have irregular prenatal check-ups. I hope my explanation helps you. This is the advice for the question "Menstruation came around October 13th," and I hope it is helpful to you. Wishing you health!
