Girls, when is it time to call an ambulance?

Girls, when is it time to call an ambulance?After lunch, mucus started coming out, and blood clots formed.It's like three births; but I always felt like I was going into labor early.This time at home, there's another one too.How do I handle this?My lower abdomen feels heavy and it's not constant.But it's not contractions.I also decided to dye my hair so I look good for discharge ?
