Patient's question:
Detailed medical condition and consultation purpose: My question is, I have taken birth control pills which disrupted my menstrual cycle, and I also touched cold water during my period, which caused it to be delayed by about 10 days. If this is the case, how should the safe period be calculated? Is it calculated from the day it's clean? Please give me an accurate and detailed answer. Thank you.First follow-up question: If the menstrual cycle is irregular, you can consider the 14th day before the next period as the ovulation period.
According to this, can't I calculate this time? But after it's clean, if I haven't used contraception for 3 consecutive days, is there any danger?
Can you tell me,
Doctor's answer:
Hello! The ovulation date for women is generally about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive for 1 to 2 days in the fallopian tube, waiting to be fertilized. Male sperm can maintain its viability in a woman's reproductive tract for 2 to 3 days, so sexual intercourse during the days before and after ovulation increases the likelihood of conception. For safety, we refer to the 5 days before the ovulation date, the ovulation day itself, and the 4 days after it as a 10-day period called the fertile window. Because sexual intercourse during the fertile window increases the chance of pregnancy, it is also known as the "unsafe period" or "dangerous period."
