Cramping at 34 weeks

Hi I'm currently 34 weeks pregnant. I just started having severe lower abdominal cramping it comes and goes.... I'm not sure if they're contractions far I've noticed the normal clear/ white discharge. When the baby moves it hurts even more..I have 3 other kids and am currently not on good terms with their father so I don't want 2 go 2 the er for nothing.
