Cervix position?

Savanna • Married November 29, 2013. TTC for 4 months.
So first of all I have no idea what I am feeling for. I know it's supposed to feel like a nose or something? Idk but the second question I have is what if you have a tiny cervix? How does that affect fertility? I have HPV and when my doctor was trying to do a biopsy he said it was super tiny and he could barely see it! So what does that mean for me?
