How Long Should I Wait For Tissue To Pass After Medication For Miscarriage?

I took 2 doses Misoprostol vaginally 2 days ago and the 3rd dose yesterday morning for a missed miscarriage. I have had bleeding like a heavy period and passed a few clots last night but not the fetal tissue. I have no cramps today just normal bleeding. Should I take the next dose of Misoprostol today or wait a bit longer? How long does it normally take for all the tissue to pass? I took Misoprostol back in November for a missed miscarriage and I passed most of the clots and tissue on the first day after taking the medicine and the rest 2 days later so this time is very different and I don t know what to expect.
