Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How many days into pregnancy can it be detected?Doctor's answer:
It doesn't matter if it's in the morning or evening. The ovulation period is approximately 14 days before the next menstrual period, when an egg is released. The egg can survive for 1 to 2 days, while sperm can survive in the uterus for 2 to 3 days. After this period, the sperm loses the ability to fertilize the egg. Therefore, we refer to the 5 days before and 4 days after the ovulation day as the fertile window, during which sexual intercourse increases the chances of pregnancy.
