I am 34 weeks pregnant was just got out of the hospital last week now I have blood spotting and every 3 count a plashing come for the baby as well as a heavy discharge what to do

I'm not quite sure what you are saying with "every 3 count a plashing come for the baby". Do you feel that you might be leaking amniotic fluid? Since you are concerned by what you are experiencing, it would be wise to contact your doctor or midwife and let them know what it going on.
