Anxiety

So for all my life my yearly pap exam has terrified me. It's irrational I know but here I am up the last 2 hours worried about it nervous poops and all. My mom, 3 sisters and an aunt have all had cervical cancer or tumors in their uterus and that terrified me. I've avoided my exam for 3 years do to fear and that just makes it worse I intend not to cancel this years exam my husband took off work to make sure I go and has went out of his way to keep me calm. Does anyone else have this issue or just me?
