Hi I am Dr Fahim and I will help you with your query
I have gone through your question. There is a bump on left side of abdomen with previous history of
hernia and you are worried that it might be
Fallopian tube pregnancy, while her periods are regular.
The type of pregnancy you are talking about is called Ectopic Pregnancy; meaning pregnancy other than its normal position which is uterus. Patient with ectopic pregnancy presents with
severe pain and mostly with missed periods, but not with swellings. So its not Ectopic pregnancy.
To me it appears to be hernia, most likely incisional if the swelling is in the previous scar. It may bulge on straining or coughing. You need to see a
general surgeon, who after clinical examination will give you diagnosis and subsequent treatment.
I hope my answer will help you, feel free to ask if you have any further queries. Do rate my answer, if you like it.
