Hi,
I would appreciate if someone has got knowledge in the above subject to give me an immediate answer.
One of my closest friends went on holidays on 28th March 2006. He stayed with his family for one month. His wife has consulted a gyaenacologist who gave her a contraceptive pill as both of them were preferring direct sex without a condom. She was taking the pills twice a week and as per him they enjoyed the sex. She started the pill on time. He came back to work on 29th April and on 1st May his wife told him that she is having stomach pain and a feeling to vomit and consulted their family doctor who gave an injection for the pain. Next day on 2nd May she was having the cramp again so she went to the doctor again and he diagnosed her and asked her to urgently to the hospital (casuality). She went to the hospital and they scanned her and told her that they have to operate her immediately as her fallopian tube is having bleeding due to ectopic pregnancy. She is operated now.
My friend is very much worried and would like to know how it happened as his wife was taking pills and how did the ovum got fertiled and reached the fallopian tube?
