If you want to try here is what you should feel. Most things in there should feel squishy and soft. If you reach in high and towards the back tou may feel something that feels a hard as the tip of your nose it will also have the shape of a small doughnut but will be long like a tube ( about 2.5cm long) This is your cervix. You should be able to feel a dimple or even a hole in this doughnut. That is the opening of your cervix and what we measure to see how dilated you are.
A few tips if you are going to try to find your cervix. Wash hands ensure that they are clean.
If it is uncomfortable stop.
Do not even think about trying to find your cervix if your waters have broken or if you think thay could be broken.
Do not try to find your cervix if you have any sign of infection.
And one last and very important tip.
Do not let anyone else try to touch your cervix unless they have some training or they are quite cute 
Letting a stranger touch your cervix when you are drunk is usually not a good idea.
Ok so that was 2 last tips
