Cervical mucus: a guide to each stage
The stages, in order
Dry/none (just after the period) → sticky/tacky → creamy and lotion-like → clear, stretchy “egg white” (most fertile) → thick and scant again after ovulation. The egg-white stage is the key fertility marker: it helps sperm survive and travel.
How to check it
Note the colour, and whether it stretches between two fingers. Clear and stretchy means fertile; tacky or dry means lower fertility. Tracking mucus is part of fertility-awareness methods — but on its own it is not reliable for avoiding pregnancy.
See a doctor if you notice
- Green, grey or foul-smelling discharge
- Cottage-cheese discharge with itching or burning
- Discharge with pelvic pain or bleeding between periods
Frequently asked questions
What does fertile cervical mucus look like?
Clear, slippery and stretchy — like raw egg white. It appears for a day or two around ovulation and marks your most fertile window.
Can I rely on cervical mucus to avoid pregnancy?
No. Mucus-only methods have a high typical-use failure rate. For contraception, use a reliable method.
