So this all happened to me maybe an hour ago. I had gone to sleep about 7 am and woke up at 4 in the afternoon (I know it's unhealthy but I don't think it's what caused it) so I got up and was about to take a shower but then my lower stomach just started hurting so I figured I needed to take a dump or something, so I went to the toilet and nothing comes out except I was really hot so I got up and my stomach started hurting even more, like that was in the top ten worst pains I've felt in my life and I decided I needed a semi cold shower. As soon as I got in I regretted it, I was sweating so much, and I tried to wash my body but it felt wrong so I managed to start washing my hair but everything was starting to turn black so I hopped out he shower and felt like I needed to throw up so I sat there gagging but I couldn't throw up, then after like 5 minutes of that I got up and checked if I needed to take a dump again, it took a while but only some hard poop came out, I started to feel a little better so I went back to the shower to wash the conditioner out of my hair but then everything did turn black, I was still in concsiousness but I couldn't see at all, so I was fumbling around and trying not to faint because that would suck to faint in the shower, and finally I was able to turn off the water and stepped out, my vision came back immidietly and I put my clothes on and waited a minute until I felt better and now I'm in my room sipping water. So yeah.. If anyone has an answe then please tell me because that was pretty scary. Also additional information is that I'm 17 and a female, also I'm on my period. This has never happened to me before
