So I went for a quick run yesterday. It lasted 5 mins and I've done that run 100 times before. (I run with my dog) and after 5 mins I started feeling very odd (at this point I'd stop to put something in the bin) and I decided not to start running again. And as I was walking home I got the worst cramps EVER! It was horrible. I felt like I was gonna throw up and I needed the toilet 💩. So when I finally got home I rushed to the toilet and I threw up 😭 I thought exercising helped, not made it worse! And it had been 2 hours since I'd eaten, so once again my periods made me throw up.
