Checking my f#%^*!$ cervix

Reva • Mother of four children in a blended family, trying for #5. I`m an RN trying to balance family and career.
I'm having issues with my cervix. I can't reach it! I'm a nurse and I can't reach my own damn cervix! Any tips on how to get to it? Maybe my fingers are just short or maybe I just have a deep vag, either way I need help!
