Patient's question:
I had my period on February 2nd and had sex on the 10th. Could I be pregnant? I took an emergency contraceptive pill, and I had a little bleeding on February 21st. It's now the 22nd and I haven't had my period yet. Am I pregnant?Doctor's answer:
The day of ovulation is generally fourteen days before the next menstrual period. Since an egg can be fertilized within two to three days after it is released, and sperm can survive for three to four days and still enter the egg, if we take the day of ovulation as the base, the four days before and the five days after are considered the risky period, while the rest are the safe period. If the menstrual period arrived on October 2nd, and intercourse occurred on the 10th, it would be the safe period, and the likelihood of pregnancy would be high.
