HOW TO ENDURE PAINS WHILE TAKING MISOPROSTOL?

I am currently taking misoprostol as prescribe by my OB due to anembryonic pregnancy, kaso while taking the medicine, di ko kaya ang sakit talaga. Di ko na alam kung alin ba talaga sumasakit. First time to get pregnant and di nabuo baby namin. Ganito ba pakiramdam ng paglabor? Paano mababawasan ang sakit? Kahit ano position ko, masakit talaga.. help me please...
