I Have A Query Doctor...Doctor Mifepristone Is An Abortifacient, Which

I have a query doctor...Doctor Mifepristone is an abortifacient, which contracts the uterus, but during abortion period for relieving the pain generally doctors will prescribe Meftal Spas (dicyclomine+mefenemic acid). Dicyclomine is an uterine relaxant. Doctor may i know the reason behind for prescribing the dicyclomine during abortion. Bothe the drugs are pharmacologically opposite to each other. Please clarify my doubt
