Excruciating period pain

Im already booked in at the docs, but just wondering if anyone else has experienced this, and what was it for you?

So I came on my period yesterday and it was genuinely the most painful thing I’ve experienced I’m 23 so had plenty of periods but this pain was something else, to the point it was making me throw up from the pain, it was completely unbearable! I normally have regular periods, and I usually get a little bit of pain the first day or too but nothing bad. Thanks in advance 🙂
