TMI PICTURES INCLUDED. Is this normal?

Rosalind • Dating my best friend! Our first baby due 8/30/15
I just had my 38 week check up today and had my first cervix check. My OB was very rough, nothing i couldn't handle by still felt unnecessary. I'm 1.5cm dialated and 50% effaced, It's been 4 hours since then and I'm still cramping and feeling a lot of pressure down there. I went to the restroom and found this when I wiped... Is this normal after a cervix check or is this the start of a bloody show? 
I also found this in the toilet... Mucus plug? Or am I completely overreacting?
