pregnant with a huge bump on my a$$

Hey ladies. I woke up this morning to a huge bump on the external
Part of my anus. TMI. I know but I never had this before. I googled and it said hemorrhoid. 😳 I'm 39 weeks and I have a scheduled c section on Wednesday! It doesn't bother me. Unless I touch it, it itch a little. I called my dr but he is busy so I'm waiting for him to call back. So til then,  How do I get this bump off?!!!!
