It’s not compulsory but since you’re sexually active, I think it’s quite important to do the test. Early detection of abnormal cells is important to prevent full blown cervical cancer. If your test is normal, the next time you need to do the test might be in 5 years (depending on what your doctor says). It was surprisingly less uncomfortable than expected, and by gynae did it really quickly too. Hugs, dear. You can do it!
