My wife and I have figured that out for her while hiking. Everything is spot on with what A2 said. My wife has really enjoyed having toilet seat covers, for sketchy bathrooms, and, we carry a couple of RV toilet chem packets to help keep down odors and break down poop when camping remote at the same spot while hunting in the backcountry. Just be careful not to carry too many as they can add weight quickly. I would primarily suggest that, if you have a partner, have a plan for contraception, other than condoms. Condoms can become heavy if carrying supplies for any significant period of time. I know many women who carry a thermometer for this purpose, and that is important because a thermometer is not part of the first aid kit on this site.
