Unless you have been keeping strict & accurate records of your cycle, it is almost impossible to know the exact day you got pregnant. Sperm are able to survive for 3 days in the vagina. Then the egg is fertilized in the fallopian tube and takes about 7 days to travel down into the uterus.
If you have further concerns about your dates, discuss them with your OB doctor or midwife during your prenatal visit.
