threatened abortion
cramping(often painless), bloody discharge, closed cervical os. small percentage will go into spontaneous abortion
inevitable abortion
obvious rupture of membranes and leaking of amniotic fluid in the first 12 wks.
what if a inevitable abortion occurs with cervical dilation,
it will likely progress to a miscarriage
