A watery discharge with a strong, unpleasant smell going on for 2 to 3 months usually points to a vaginal infection, most often bacterial vaginosis, though trichomoniasis or another infection can look similar. Normal discharge doesn't carry a smell like this, so it's worth getting checked rather than waiting it out.
Next Steps
A vaginal swab test will show exactly which infection this is, so the right treatment can start. Please see a gynaecologist this week for the swab and an examination.
Health Tips
See a doctor sooner if you notice itching, burning, pelvic pain, or bleeding between periods.
