Answer:
Answer is option B (an ectopic pregnancy).
A history of pelvic inflammatory disease or tubal ligations increases a woman's risk for an ectopic pregnancy.
Explanation:
Conception occurs when the ovum (egg) released from one of the ovaries during ovulation meets a sperm in the fallopian tube. The fertilized ovum usually moves from the fallopian tube into the uterus and gets implanted in the endometrium (uterine lining), where it develops into an embryo.
In an ectopic pregnancy, the fertilized ovum develops in one of the fallopian tubes, outside the uterus. The blockage in the tube or the inability of the tiny hairs inside the tube to sweep the fertilized ovum towards the uterus prevents the movement of the ovum into the uterus and results in ectopic pregnancy. Usually, the embryo growth is halted and it dies since the fallopian tube can not support the growing embryo. The ectopic pregnancy causes severe pain, rupture of the fallopian tube and internal bleeding.
The risk factors associated with an ectopic pregnancy are endometriosis, a history of pelvic inflammatory disease or tubal ligations (sterilization method by tying of tubes), defects of the fallopian tube, pregnancy occurs as a result of a failed tubal sterilization, etc.
Placenta previa is a pregnancy complication in which the placenta partially or completely covers the cervix by lying low in the uterus. Preeclampsia is also a pregnancy complication that occurs due to the sudden increase in blood pressure, presence of protein in the urine and results in swelling of face and limbs. Gestational diabetes is diabetes developed during pregnancy.
