Patient's question:
I want to ask if it's true that sperm and egg first fuse, and it takes seven to ten days for implantation to occur. If I had intercourse before June 15th, is there no chance of pregnancy? If I had intercourse on the 18th and took a birth control pill on the 19th, it means I couldn't prevent the fusion of sperm and egg that had already occurred before the 18th, and I couldn't stop the implantation of sperm and egg, so I got pregnant. They said it implanted around the 20th. Since the child can develop normally, taking a birth control pill on the 19th would be useless. If the birth control pill had worked, I wouldn't have gotten pregnant, right?Doctor's answer:
In this case, there's no need to be too anxious at the moment. You can have a blood HCG test 10 days after sexual activity. Blood HCG can help confirm or rule out early pregnancy at an early stage. If the menstrual period still hasn't arrived after ruling out early pregnancy, you can have a six-item sex hormone test. Based on the results of the sex hormone test, you can adjust your condition to promote the onset of menstruation. This is the complete introduction to "Is pregnancy the result of sperm and egg first combining?" In the end, we wish the patient a speedy recovery and a healthy life.
