Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How can I know if I'm pregnant for a month?Doctor's answer:
The time of pregnancy is calculated from the day the menstrual period ends. In medicine, it is generally counted from the start of the last menstrual period to determine the number of days of pregnancy. That is to say, if on February 1st, when your menstrual period should have arrived, you find that it hasn't, and you suspect you might be pregnant. According to medical calculation, you would already be one month pregnant. If your menstrual cycle is 28 days, this means you have been pregnant for 28 days.
