I had ta sonogram last week. doctor didn't see gest. sac or anything.had heavy petting 2 months ago and still suspect to be pregnant.is it possible?

Can do a preg. test: Symptoms such as nausea (with or without vomiting), some fatigue (feeling less energetic), a sharper/stronger sense of smell, mild soreness/swelling of the breasts, and maybe some food aversions and cravings, can happen with other conditions, not just with pregnancy. However, if the pregnancy test was done less than 2 weeks after possible conception, a woman can repeat the test a week later.
