If you have intercourse two days before your period, you will not get pregnant in most cases, and it is a safe period of intercourse. If a woman has intercourse two days before her period, and if her period comes normally two days later, she is definitely not pregnant. If a woman needs to get pregnant, intercourse should be near the time of ovulation. Ovulation is 14 days before the next menstrual period, and intercourse is usually possible within three days before and two days after ovulation, when the probability of pregnancy is highest. However, if a woman does not intend to become pregnant, it is advisable to use contraception even if her period is close to the onset of menstruation. This is because a woman’s ovulation can be affected by various factors such as environment, emotions, mental and mood, which can produce abnormal ovulation. So if you want to achieve no pregnancy at all, it is still recommended that you must use contraception every time you have sex in order to truly achieve contraception.
