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 on June 7th and you have a 28-day cycle, your ovulation period should be around the 20th. If your cycle is 30 days, it would be around the 22nd.If you started taking birth control pills on the 19th, it should have been effective. The statement says that since you are developing normally, it proves that the birth control pills didn't work. If they had, the pregnancy would have been miscarried.
What does this mean? Did you get pregnant before the 19th? But my last menstrual period was on May 30th. I don't understand why they calculated my last menstrual period as June 7th. They said the early MRI had very little error.
Doctor's answer:
According to your description, I feel that your question is quite confusing, but I want to tell you that the estimated date of conception should be calculated from the first day of your last menstrual period.
