Membrane sweep

I’m 40+3 weeks pregnant. Contracting every 6-8 minutes. In absolute agony! Lost loads of my mucus plug already. Just been to see my midwife and she did a sweep for me. She said I’m 2-3cm dilated which is great but after she did it there was a lot of bright red blood! She said it’s normal and to worry if there’s more than a teaspoon but everywhere I’ve read says that it’s normal to have spotting or brown blood. I’ve been having bright red blood! Is this normal? Has it happened to anyone else?
