Worst period so far

This month's period was the worst. I got it during my exam day. Eveything was well until in the middle of exam when my cramps become worse. I couldn't move, I couldn't breathe, but I didn't tell anyone. I felt nauseas. I couldn't complete the exam properly. When it finished I told my Friend but still suffering in pain. I couldn't even form tears to cry. Then it happened, i vomited a lot. My friends rushed to call my mom and I was brought my group of friends to the office in school to wait. My class teacher was there and the school discipline teacher also kept checking on me. When my mom can, I told her I don't think I could take the next paper but after going and drinking 100plus, putting ointment and resting, I've decided to try and take the exam and so I did. On this day I realised how much my friends care for me and how they took care of me even the one that I used to hate her in the first year of school cause she bullied me. Have you experienced vomiting during your period?
