In the case of increased and yellowish discharge in the second trimester, the first thing you should do is to go to the hospital for a vaginal discharge test. If the discharge test does not show any abnormality, no special treatment is needed, only regular prenatal checkups. If the discharge reveals vaginal inflammation, you should be given the appropriate medication. More common during pregnancy is mycosis fungoides, which is an infection with Pseudomonas aeruginosa. The usual medication used in this case is clotrimazole suppositories, which are placed vaginally, one capsule per night for 7 days, and are more effective. However, mycosis vaginalis is prone to recurrence and can come back again even after it is cured, and it is prone to premature rupture of the fetal membranes, so it must be treated actively. If pregnant women feel pain and itching in the vulva and experience increased vaginal discharge, they should go to the hospital promptly.
