The slight pink color of the leucorrhea in early pregnancy may be caused by normal physiological factors, but it may also be caused by ectopic pregnancy, pre-eclampsia, gynecological diseases, etc. You need to go to the hospital in time to check the serum HCG and improve the ultrasound examination to make a clear diagnosis and then carry out symptomatic treatment. Common causes and treatment methods: a. Physiological factors After the formation of the fertilized egg, it will gradually migrate from the fallopian tube to the uterine cavity for implantation in the endometrial muscles and blood vessels. Therefore, in some women, the fertilized egg will cause the rupture of small blood vessels in the endometrium during implantation, resulting in a certain degree of vaginal bleeding, which may appear as a slight pink or brown discharge that will gradually disappear in 1-2 days. Pathological factors 1. Ectopic pregnancy: In the case of ectopic pregnancy, the estrogen and progesterone in the body are low and the endometrium lacks sufficient estrogen to nourish it, resulting in a small amount of endometrial shedding, which causes vaginal bleeding, but the amount of bleeding is usually less than the amount of menstruation. Generally, when bleeding is mild, medication or surgery can be used. Drugs such as methotrexate are usually used, and serum HCG and ultrasound need to be rechecked regularly during and after treatment. 2. Pre-eclampsia: If the gestational sac slightly peels off the uterine wall, it can lead to bloody discharge, which can be manifested as pinkish leucorrhea. Patients need to take proper rest, reduce the amount of activity, and supplement more iron-rich foods such as animal offal, etc. Hormones such as progesterone and progesterone can be used for fetal preservation treatment under the guidance of a doctor; 3, gynecological diseases: hormonal changes are greater in early pregnancy, and gynecological diseases such as vaginitis, cervicitis and cervical polyps are more likely to develop, making the local mucosal tissue congested and edematous, causing rupture of capillaries, which in turn leads to bloody leucorrhea. Patients should seek medical attention and use timely antibiotic suppositories, gels or vaginal soft capsules under the guidance of a doctor to control inflammation with local action. The patient needs to pay attention to hygiene habits and vaginal douching is strictly prohibited. Attention in early pregnancy can observe the color of your own leucorrhoea to detect the lesion in time. Avoid overworking and staying up late in daily life, and relax to avoid uterine contraction and aggravate the symptoms.
