What Is Vaginal Discharge and Why Does It Happen?
Vaginal discharge, also called leukorrhea, is a natural fluid made by the glands in the cervix and vaginal walls. It keeps the vagina lubricated and clean by flushing out dead cells and bacteria, maintains the right pH balance, and prevents infections.Normal healthy discharge is usually clear or milky white, slightly sticky, and has little or no smell. The amount and texture change throughout the monthly cycle because of the rise and fall in hormones, especially oestrogen and progesterone.
How Does Vaginal Discharge Look Just Before Your Period Starts?
In the days leading up to menstruation (the luteal phase), progesterone levels rise after ovulation, and this affects the discharge noticeably:- It usually becomes thicker, creamier and sometimes pasty or sticky.
- Colour is mostly white, off-white, cloudy or slightly yellowish.
- The quantity often decreases slightly just before bleeding begins.
- Some people notice light pink or brown spotting because of old blood.
- There might be a mild musky smell, but nothing strong or unpleasant.
- You may also feel typical PMS symptoms such as bloating, breast tenderness, cramps and mood changes.
What Changes Happen to Vaginal Discharge in Early Pregnancy?
As soon as conception happens, the body starts producing more oestrogen and progesterone to support the pregnancy. This quickly changes the discharge:- The amount increases noticeably, often a lot more than usual.
- Consistency becomes thinner, watery, milky or slightly slippery (sometimes compared to raw egg white).
- Colour remains clear or milky white and is relatively consistent.
- It is almost always odourless or has only a very mild scent.
- The increase may begin as early as 1-2 weeks after conception, even before a missed period.
- This extra discharge helps form the mucus plug that protects the uterus from infection throughout pregnancy.

Is Thick White Discharge Always a Period Sign or Can It Mean Pregnancy?
Thick white discharge is much more common just before your period because high progesterone at that time makes the mucus thicker. That said, some people do get milky white discharge in very early pregnancy as well.The only way to know for sure is to look at the whole picture, like the quantity, how thin or thick it feels, any other symptoms you have, and most importantly, whether your period arrives on time or not.
Most individuals start noticing the pregnancy-type discharge around 7 to 14 days after ovulation, which is roughly the week before the expected period. That is why it can feel so confusing, as both situations can overlap in timing.
What Other Reasons Can Cause Vaginal Discharge to Change?
Yes. Sometimes changes in your discharge aren’t about your period or pregnancy at all. There can be a few other things going on in your body that affect it:- Hormonal birth control: If you’re on the pill, patch, or other hormonal methods, you might notice that your discharge changes. It can become thicker, a little more slippery, or just different from what you’re used to.
- Stress: Life can get hectic, and stress doesn’t just affect your mood. It actually messes with your hormones, which in turn can alter your usual discharge pattern.
- Infections: Yeast infections or bacterial vaginosis can change your discharge in noticeable ways. You might observe it turn yellow, green, or grey, or develop a texture like cottage cheese.
- Sexually transmitted infections (STIs): Some STIs can also cause discharge that looks different. It may look frothy, coloured, or accompanied by pain during urination or intercourse.
