You have to time your pooping. Why? Because there is a string hanging out of your vagina. It's like a little tail, and it's also like a little poop magnet. If you try to poop without also changing your tampon, you risk getting poop on the tampon string. It's not super common, and you can avoid it by being careful, but it's a lot to manage when you can't even see most of the area in question. Also, it is so so disgusting when it does happen that it's worth being hypervigilant. So you have to like pull the string up, poop, wipe very carefully. Sometimes when you poop the tampon starts to come out a little, like it's pushed out by whatever kind of intravaginal pressure results from the poop coming out. Then you have to change the tampon, because having it partway out hurts. So it's important to time your poops so you can just change tampons at the same time and not have to worry about any of it. But, as a coffee drinker, sometimes this is not so feasible. Even if it is, there is still the toilet full of bloody poop.
The reason you have to time the poops is because if you take the tampon out too early it scrapes. This is not so much painful as just gross and unpleasant, like imagine filling your mouth with cotton balls. The tampon has to be soaked enough with blood so that it's moderately lubricated when you pull it out, otherwise it's rough cotton dragging across dry parched vagina. This is not such an issue on your heaviest days, but there are a good 3-4 days every month where you have to be careful of this.
It's funny because like you would imagine the blood coming out of your vagina during menstruation to be a bit like the blood that comes out of your arm or leg when you get cut or scraped. But it's not. It's got all sorts of chunky tissue in it. Mostly they look like little jellies, or little blobs of glue, but sometimes they're more textured. These chunks don't sink into the tampon, but rather just kind of cling to it, so when you pull the tampon out they like to wave and say hello. Sometimes I just sit on the toilet and peer between my legs as they hit the water. They look like some kinda sick cross between a jellyfish and a maggot, only blood red, and when they hit the water they sink to the floor of the toilet, leaving a trail of bloody water coming off of them. It's kind of pretty, only also disgusting. I read once that 20% of pregnancies end in miscarriage in the first trimester, and that the women don't even know it because they're passed with the menstrual flow. Consequently, I always wonder when I see those chunks if one of them may be my son or daughter.
Yeah yeah yeah. We've all heard how bad they are. You know what? No you fucking haven't. Menstruation is the lining of your uterus--all those chunks we talked about--being shed. It's sort of like an internal scab being ripped off--and that's what it feels like. Imagine the lining of one of your internal organs being sloughed off. The closest thing that I can direct you to for an example of what this feels like is when you are bleeding from a wound. Do you know how when you cut yourself, the aching feeling of losing blood? Great, now imagine your entire pelvic area feeling like that. If you let yourself focus on it, you will inevitably think Oh god, I am going to bleed to DEATH.
