Your body produces cervical mucus (also called cervical fluid) throughout your menstrual cycle. By learning to observe and interpret these changes, you can identify your most fertile days—without any tests or devices.
Unlike BBT, which confirms ovulation after it happens, cervical mucus changes before ovulation—giving you advance warning of your fertile window. This makes it invaluable for timing intercourse.
| Type | Appearance | Fertility Level | Cycle Phase |
|---|---|---|---|
| Dry/None | No visible mucus, dry feeling | ❌ Not fertile | Right after period |
| Sticky | Thick, white, tacky, breaks easily | ⚠️ Low fertility | Early follicular |
| Creamy | White/yellowish, lotion-like | ⚠️ Possible fertility | Approaching ovulation |
| Egg White (EWCM) | Clear, stretchy, slippery, raw egg white texture | ✅ Peak fertility! | 1-2 days before ovulation |
Estrogen levels control your cervical mucus:
Some women produce less obvious EWCM. Check internally (near the cervix) rather than just externally. Also ensure adequate hydration—dehydration reduces mucus production.
Yes! Antihistamines, decongestants, and some fertility medications (like Clomid) can dry up cervical mucus. Mucinex (guaifenesin) is sometimes used to increase mucus.
Watery mucus is also fertile! It typically appears just before EWCM and indicates rising estrogen. Both watery and EWCM are "fertile quality" mucus.
