yup yup yup
did exactly the same thing playing netball a number of years ago.
I was standing on tippy toes shooting the hoop and it felt like someone had kicked me in the calf very hard while wearing steel caps.
I was hobbling around on an upended broom for days until I got someone to take me to the docs and then I upgraded to a pair of crutches. It took weeks to recover.
It hurt like crazy, but sorry, it's not as bad as child birth.
I hope you get better soon.
