What does it feel like getting on prostaglandin?

First of all, HAPPY MOTHER'S DAY! ❤️❤️❤️🎉

I'm 40 weeks pregnant, my due date was actually today. My cervix is 50% thin, the baby is front facing and in my pelvis ready to birth..... The OB seems to want to induce me on Wednesday, bc I'm 4'11 and the baby is about 7.5 lbs. We don't want to do C-section. He plan to give me prostaglandin every 4 hours and wait until I'm at 3cm. Has anyone been on my shoes? What should I be expecting from this?
