Charles B. Penrose, A Text-book of Diseases of Women
“ The fear of pregnancy after illicit coitus sometimes produces it.In some unusual cases amenorrhea is present without any discoverable cause. The woman may be in perfect general health, and the sexual organs may be well developed, at least so far as can be determined by physical examination.In amenorrhea there is often a general periodical disturbance that marks the times at which the menstrual bleeding should occur. There may be headache, flashes of heat, nervousness, nausea and vomiting, and a feeling of fulness and pain in the pelvis. ”
