Should I be seen ?

I don’t want an unnecessary er trip but I’m almost 34 weeks, I’m high risk for placental abruption and went to the bathroom, wiped and got this. I was in the hospital at 30 weeks for bleeding and contractions, they had to stop the preterm labor and give steroid shots. I’m having a little cramping now ... kind of like contractions but not too intense ... should I wait until contractions get worse or I fill a pad with blood or should I just go in?
