I started my period the day before my surgery (of course!). I was embarrassed but the nurses were so great, they were very accommodating and didn't make it awkward at all. You do have to wear there stretchy white undies and use pads, no tampons. And they do catheterize you, which is uncomfortable but for me came out as soon as I was able to get up and walk. After they took my cath out I was able to go into the bathroom and get cleaned up and everything was fine. It's really only awkward for us as the patients, my nurse told me they see it all time with us being so nervous and whatnot before surgery (people starting early) so no worries
