Therefore, a female can become pregnant from having vaginal intercourse up to five days before ovulation. In addition, the egg lives a day or two after ovulation. Therefore, she can get pregnant for two days, or a little longer, during and after ovulation. This means there are approximately seven or eight days each month when a girl can become pregnant from vaginal intercourse. They include the five days before, the day of ovulation and the two days after.
Females can and do become pregnant from having sex during their menstrual period.
In most cases, the first sign of pregnancy is missing a period. Other signs include nausea, vomiting, or feeling tired all the time, sore and swollen breasts and having to urinate more often than normal. If you think you could be pregnant, see your private doctor, county health department's family planning clinic or a Planned Parenthood affiliate for a pregnancy test and check-up. While a missed period may be due to illness or stress, the most common reason is pregnancy. If you are pregnant, you will need the care of a professional.
