Vaginal discharge, or leukorrhea, is composed of fluid secreted from the cervix and vagina, epithelial cells shed from the vagina, and normal vaginal flora. Yellowish leukorrhea during pregnancy requires vigilance of combined vaginal inflammation.
It is normal for leucorrhea to increase after pregnancy: after pregnancy, due to the increase of estrogen level in the body and rich vaginal blood flow, leucorrhea increases, usually milky white, which is a normal physiological phenomenon. The leucorrhea will be more near the delivery period, jelly-like or egg-white like.
If the leucorrhea suddenly increases and changes in its nature (watery, mucus-like, bean curd-like, foamy, smelly, bloody, yellow or yellow-green); or if there is painful urination, painful intercourse, painful vulva, itching, burning sensation, flushing or even swelling of vulva, etc., it is abnormal and you should be alert to the possibility of combined vaginal inflammation. vaginitis (topical vaginal treatment with clotrimazole or mycoplasma), trichomonas vaginitis (metronidazole treatment and treatment of sexual partners), bacterial vaginitis (BV, metronidazole or clindamycin treatment), positive Chlamydia trachomatis (azithromycin or erythromycin treatment, mainly transmitted by sexual intercourse), positive mycoplasma (normal flora component of female genital tract, can be left untreated).
In summary, increased, milky white leucorrhea usually occurs during pregnancy and is mostly normal. However, if the leucorrhea is yellowish, smelly or accompanied by other symptoms such as itching, pain and burning sensation in the vulva, it may be combined with vaginal inflammation, and the cause needs to be promptly identified by a doctor.
