What are the chances of being pregnant if five days after sex you having back pains and your breasts tender but not nipples?

The symptoms you mentioned, such as back pain and tender breasts, can be early signs of pregnancy. However, it is important to note that these symptoms can also be associated with other factors such as hormonal changes or upcoming menstrual period.

The likelihood of being pregnant after having unprotected sex depends on several factors, including the time of ovulation and the effectiveness of the contraceptive method used. If you had unprotected sex during your fertile window, which is usually around the middle of your menstrual cycle, there is a possibility of pregnancy.

To confirm whether you are pregnant, it is recommended to take a pregnancy test. Pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy. Home pregnancy tests are widely available and can be taken a few days after your expected period. For a more accurate result, you can also consider getting a blood test done by a healthcare professional.
