What is the engineering point of view for the PMS or menstrual pain/cramp?
The uterine ligaments, joints, and the pelvic muscles lose their flexibility and elasticity ( a lack of Prostaglandin E1 produced in the local tissues and Nitric Oxide released by the parasympathetic nervous endings in the local arteries) during the high-temperature period (the Luteal Phase), 2 or 3 days after ovulating, as shown in http://www.actiontao.com/image/cycle.jpg due to the deficiency of DHEA and testosterone hormones in the bloodstream. 
The dynamic uterine contraction or movement, no matter how light or heavy (like sexual orgasm), will load an extra stress on the ligaments, joints, and muscles in the pelvic area. The local nerves in the inelastic and inflexible tissues will respond to the extra stress (the material strain-stress produced by the movement, displacement or volumetric change of the uterus)  with pelvic cramps and pains which alert the Central Nervous System to drive the patient nut.
Thus, PMS, menstrual pains or cramps occur when the nerves in the ligaments or tissues in the pelvic area lack of relaxation/elasticity hormone Prostaglandin E1 or lose their elasticity or flexibility.
Why elevation of progesterone, during the luteal phase, by either the endogenous (or so called bio-identical) or artificial from birth control medication causes so many problems such as PreMenstrual Syndromes (stress, anxiety, depression, low abdominal pains, cramps, migraine, intercourse pain and vulva abrasion), blood clots, low libido, vaginal discharge, and no sexual orgasm.
