How effective was round 2 misoprostol for you/someone you know?

Had my first dose of misoprostol 7 days and passed about 60-75% of the tissue in my uterus. Had heavy bleeding for about 5 days that tapered off and the last 2 days I’ve had spotting. I went in for a FU ultrasound today and my OB wants me to take a second dose of misoprostol tonight. Anyone else have effectiveness with a second round? I really want to avoid a d&c. Also, how uncomfortable was the second round compared to the first dose? Thank everyone ❤️
