Misoprostol

I’m supposed to be 9+3 today. 3 weeks ago I went in for blood work. My HCG level came back low. Then I had 2 more blood work that showed I had a slow rising HCG. I went in for an ultrasound 2 weeks ago at 7+2 weeks. They only found an empty sac that measured 5+2 weeks, told me to come back in 2 weeks. Today I went in for another ultrasound. My sac remained empty and measured at 6+1 week. I was prescribed misoprostol to start the miscarriage at home. I’m hoping that anyone with similar experiences can share their experiences with misoprostol. What was it like for you? How many dosage did you have to have before you passed the tissue? How painful was it? Was it bad or not too bad?
