In the Science notes. there were some mentioning of ectopic pregnancy but they were very vague, thus I decided to do a bit of research on ectopic pregnancy.

An ectopic pregnancy is a pregnancy that occurs outside the womb (uterus).  It is a life-threatening condition to the mother. The baby (fetus) cannot survive. Ectopic pregnancies occur in 1 in every 40 to 1 in every 100 pregnancies. The most common site for an ectopic pregnancy is within one of the tubes through which the egg passes from the ovary to the uterus (fallopian tube). However, in rare cases, ectopic pregnancies can occur in the ovary, stomach area, or cervix.This is severely threatening to the life of not only the foetus but also the mother. The foetus would be unable to develop properly and would cause the rupturing of the fallopian tube in the long run. Fortunately there are some symptoms to find out if someone has ectopic pregnancy. These symptoms include abnormal vaginal bleeding, low back pain, mild cramping on one side of the pelvis and more. If detected the mother should be immediately sent to a hospital for treatment immediately.

Those were just some very basic facts that I have uncovered during the research and have indeed brought me some great information
