I have had two experiences with misoprostal. Both were very different to what you are describing.
Miscarriage 1 (8.5 week sized foetus at 12 weeks)
- Took oral dose of two misoprostal tablets at about 4pm. Some time in the middle of the night I had intense cramping and was fading in and out of consciousness, went to the toilet and passed what I imagine to have been the sac along with some clots. I thought at the time it was not much stuff to have come out, but figured it must be it.
- Two days later (again in the middle of the night) had the same thing (cramping and in/out of consciousness), went to the toilet and I swear I exploded out huge chunks (possibly the placenta??) and lots of clots of varying sizes. The bathroom looked like the scene of a horror movie afterwards
- There was still a small amount of retained product so I was given another dose a week later which did absolutely nothing at all - ie no cramping or anything.
Miscarriage 2 (16.5 week sized foetus at 20 weeks)
- This one was done in the hospital. I was given two misoprostal tablets vaginally every couple of hours from 10:30 AM. I started getting some cramping at around 4PM, it became quite intense around 6pm and I delivered my baby at around 8pm.
I am not sure whether the oral vs vaginal thing made a difference or I just knew to be a little more controlled second time round. But in either case, it happened within 12 hours, not weeks.
