It was not given precisely how many days after the intercourse you took the home pregnancy test. If it is taken too early, then it might be false negative (a negative result when the actual condition that is controlled by the test is positive).

Most of the home pregnancy tests would show the exact condition if taken 21 days after the intercourse to minimize the chances for false results. Please note that there are more sensitive tests that might need several days less to detect pregnancy.

The symptoms you reported (lower back pain, headache, weight gain, increased appetite, cramps in the lower part of the stomach) are not considered sure signs of pregnancy. Therefore, pregnancy cannot be either ruled out or confirmed based on these symptoms.

You are advised to visit your gynecologist where a physical examination would be done, and laboratory hormonal tests would be taken. In the end, an ultrasound scan might solve any doubts about possible pregnancy.
