Hello Thanks for posting your query. Usually, one of the first symptoms of an ectopic pregnancy is pain in the lower abdomen, with or without some vaginal bleeding. A lump caused by an ectopic is hardly ever felt through the abdomen, because it is usually quite small and is still confined to the pelvis. Your symptoms seem to be of pregnancy in general. If you have any pain at all or bleeding, just go to the emergency. If there is suspicion of ectopic, all hospitals arrange an emergency scan. However, as of now, I do not see any cause for concern. At 7 weeks, neither an ectopic nor an intrauterine pregnancy can be felt through the abdomen, so I presume it is nothing much. Sometimes women may develop an ovarian cyst which can become very big. As I said, if you feel any sort of pain, do go and see your doctor straight away. Best wishes.
