There have been people that feel the same as you. The only suggestion I could make is to try a cup with more length for an easier reach.
Do you use a cup now (or at least trying to use)? Which cup is it? Have you located or tried to locate and measure your cervix?
If you are able to reach your cervix, take note how far you can/need to insert a finger to reach it and then get an approximate measurement using a ruler against the noted mark on your finger/hand. (Method Two in the link below)
This will give us a better idea of which cups might work for you.
