Pink discharge is often seen at the beginning of your cycle. During early pregnancy, pink discharge also signifies implantation bleeding, which is mostly normal.
A slight tear in the vagina or cervix after intercourse also produces pink discharge.
From bright red to a dark-rust color, red discharge is common during menstruation. Spotting, or light bleeding, also occurs due to hormonal changes and some birth control methods.
While some have irregular periods, inter-menstrual bleeding can signify a health issue.
If you have gone through menopause and are suddenly experience bleeding, see a doctor because it may be a sign of endometrial cancer.
White discharge is usually a sign of healthy lubrication. However, if it is thick, white, and accompanied by a strong odor, it may be due to a yeast infection.
Yeast infections cause itching and irritation of the vulva (the external part of the vagina). Fortunately, yeast infections are easily treated with over-the-counter medication.
Yellow to green
If the discharge has a slight yellow hue, it usually is a response to your diet or certain dietary supplements. But if it takes on a darker shade of yellow or is green in color, it is likely due to bacterial infection or sexually transmitted disease.
Chlamydia, gonorrhea, or trichomoniasis are examples of what you may have. If it has a foul odor and thick texture, see a doctor immediately.
