Patient's question:
However, this method of determining ovulation isn't always accurate. Generally, ovulation occurs about 14 days before the next menstrual period. If your last menstrual period was June 7th, and you have a 28-day cycle, your ovulation period would be around the 20th. If your cycle is 30 days, it would be around the 22nd.If you took the contraceptive pill on the 19th, it should have been ineffective. The statement suggests that if the baby is developing normally, it means the pill didn't work. If it had, the pregnancy would have been terminated. This refers to whether you were already pregnant before the 18th, or if you had intercourse on the 18th and took the pill on the 19th, which might have had some effect. Or, if you took the pill after the 19th and had intercourse on the 22nd, which might have had no effect, allowing the baby to develop normally.
The doctor said I got pregnant after taking the pill and having intercourse again. Based on the size of the gestational sac, it was calculated to be 36 days, which aligns with the day after my last menstrual period ended. I can share my ultrasound results if someone could help me calculate the likelihood of delivery accurately. Thank you in advance for your help—I will offer a generous reward.
The ultrasound was done on July 13th. Could you estimate the day with the highest probability of delivery? I understand that pregnancy is calculated from the last menstrual period, but I want to know whether the error in early MRI refers to the difference between the ultrasound and the actual delivery date, or the difference between the MRI and the delivery date itself. I hope that no matter who answers, they can explain all my questions together.
Doctor's answer:
In your case, which day has the highest chance of delivery is uncertain, and it's not possible to confirm it. It's best to focus on ensuring the health of the fetus during pregnancy. It is recommended to eat less spicy food, quit smoking and drinking, and take folic acid tablets properly three months before and after pregnancy. Regular prenatal check-ups are essential to ensure the health of both the fetus and the mother, and consult a doctor immediately if any issues arise. A higher chance does not necessarily mean it will be successful.
