If you have certain symptoms then please do request a smear. Your nurse at your gp should be able to do this. It does not matter that you are only 21. Please request it. It only takes a few moments and is just a little uncomfortable.

Smear test is used to screen for cervical cancer. If you have symptoms indicative of that then ask for a colposcopy.
Not sure about ovarian cancer- blood test, biopsy? But not smear test.

Don't forget that a smear is for cervical cancer. I'm in Wales so we have an early screening age range.
Are you due for a follow up visit?

A smear test might not be the right test for your symptoms. It's probably best to have a discussion with your gp about what the test results mean and where you go next. It might be that you do need a smear but there may be other things that are more appropriate.

This site has some good information about ovarian cancer.
