Membrane sweep

Could this bit be a part of my mucus plug ? I’ve lost a part of it about 2 days ago. Also is this amount of blood and color normal after a sweep? Also been cramping a lot pretty often. They’re not SUPER painful lol. I’m a ftm and not too sure what contractions should feel like or how painful they will be. They feel like period cramps. I had my appointment today and they said I was 5cm. Thank you in advance for your input and advice !
