I hope you have gotten a negative and things are less scary/worrying.
I was also a little shocked by my GP's seriousness when I went last friday about prolonged bleeding. I'm 34 and expected him to say it's normal not to worry.. instead he made me go to hospital for blood test (as bloods would be tested quicker as lab there), and is referring me for internals, ultrasound etc.
I know having been through the fear over a breast lump that turned out to be benign that I need to kepe my worry under control.. but it's hard.. My mum had a hysterectomy young and followed by breast cancer. She died at 59 from follow ups, and now I wonder why she had the hysterectomy... but don't know.
good luck and remember we women are strong!
