Cervix is too high to reach??

Hey ladies, I've been trying to check my cervix and track, but I cant seem to reach it!! Maybe my fingers are too short, I'm not sure. I'm purchasing sperm from the us and self administering it in canada, so I dont have a SO that could check it for me. I've tried putting my foot up on the tub and toilet seat, squatting, sitting on the toilet.. bearing down and checking. Do any of you have the same issue!?
