Discharge Through Your Cycle
Normal discharge changes through the menstrual cycle as hormone levels shift. It is often light after a period, becomes more plentiful, thin and slippery just before ovulation, then thicker and less noticeable until the next period. Cycles vary, so learn your own pattern and see a clinician about odor, itching, pain or unexpected bleeding.
How to use it
- Find your current phase in the map below; day 1 is the first day of your period.
- Read how discharge often looks in that phase and what else can change it.
- Notice your own pattern over a cycle or two, since timing varies between people and between cycles.
- Contact a clinician for a change in color or odor, itching, pain, bleeding between periods, or if you might be pregnant.
Reference
| Cycle phase | How discharge often looks | Worth knowing |
|---|---|---|
| Period (from day 1) | Menstrual blood; discharge is hard to see. | ACOG suggests pads or tampons that are deodorant-free and have no plastic coating. MedlinePlus lists a forgotten tampon as a cause of foul odor. |
| Just after the period | Often little discharge. | Bleeding that continues or returns between periods is worth having checked, per MedlinePlus. |
| Approaching ovulation (around mid-cycle) | More discharge that becomes clear, thin and slippery. ACOG describes the amount noticeably increasing just before ovulation. | MedlinePlus lists ovulation as a normal reason for more discharge. |
| After ovulation until the next period | Less discharge that becomes thicker and less noticeable, per ACOG. | Can look white or pale yellow on underwear, since MedlinePlus notes clear mucus turns white or yellow when exposed to air. |
| Any time in the cycle | Sexual arousal and pregnancy can increase normal discharge, per MedlinePlus. | A change in color, odor or consistency, or itching or pain, is a reason to see a clinician. |
Cycles are not identical
Cycle length and timing differ between people and from month to month, so treat these phases as a general pattern rather than a calendar.
Vaginal bacteria shift too
Tracking 32 women for 16 weeks showed vaginal communities can shift quickly with the menstrual cycle and sex, even in healthy women (Gajer, 2012).
Not a birth control method
ACOG notes that mucus-based fertility awareness is much less reliable with typical use than with perfect use. Talk to a clinician about birth control or about planning a pregnancy.
When to get checked
See a clinician for discharge that is gray, green or yellow-green, has a strong odor, or comes with itching, pain or fever, and for any bleeding between periods or after sex.
How this tool works
This is a fixed reference map built from ACOG and MedlinePlus descriptions of how cervical mucus and discharge change with hormone levels. Phases are described in general terms, not exact days, because cycle length differs between people. It has no inputs, gives no result, and is not a birth control or conception method.
Frequently asked questions
Why does my discharge change during my cycle?
Hormone levels rise and fall across the cycle, and the cervix responds by changing how much mucus it makes and how it looks and feels. MedlinePlus notes that the amount of mucus varies during the menstrual cycle because of these hormone changes.
What does egg white discharge mean?
Clear, thin, slippery discharge that some people compare to raw egg white usually appears around ovulation. ACOG describes cervical mucus increasing and becoming thin and slippery just before ovulation. It is a normal pattern and needs no care unless it comes with odor, itching or pain.
Is white discharge before my period normal?
Thicker, less noticeable discharge after ovulation and before a period is a common normal pattern, as ACOG describes. If it turns clumpy, gray or green, smells strong, or comes with itching or burning, see a clinician to find out why.
Why do I have so much discharge on some days?
Ovulation, sexual arousal and pregnancy can all increase normal discharge, according to MedlinePlus. A sudden change in amount together with a change in color, odor or consistency is a reason to contact a clinician.
Can discharge tell me if I am pregnant?
No. MedlinePlus notes pregnancy can increase discharge, but discharge before a period and in early pregnancy can look alike. A pregnancy test is the reliable way to check, and a clinician can advise you on when to test.
Can I use discharge changes as birth control?
Not on their own. ACOG reports that with typical use of fertility awareness methods, 12 to 24 out of 100 women become pregnant in the first year. Talk to a clinician about birth control options that suit you.
When should I see a clinician about discharge?
Contact a clinician for a sudden change in color, odor, amount or consistency, itching, redness or swelling, sores, burning when you pee, fever or pelvic pain, or symptoms that last longer than a week, as MedlinePlus advises.
