TMI ..first time checking cervix

S.J. • Mother of boys. Baby boy Luke is #5 ❤️ due Sept 2018
So, I have never checked before but decided it will help me know optimum BD time. I ovulated on 10/1, so I know I am not ovulating.
I have small hands, but I almost couldn't reach it with my middle finger, so I put "high". It felt like a hole/slit and I was able to slip the tip of my finger through without forcing, so I put "open". Lastly, it felt firm, but squishy, so I put medium. Do these sound like correct answers for what I described and does it sound correct for 2DPO?
