It is possible to have a child with trichomoniasis, which means that you have trichomoniasis during pregnancy. Trichomoniasis is mostly transmitted through sexual intercourse and can easily cause preterm abortion or embryonic arrest in early pregnancy. If you get trichomoniasis early in pregnancy, you can use two tablets of metronidazole placed vaginally every day, which usually cures it in 7-10 days. Put sanitary products in the sun or boiling water to avoid cross-infection, and do not have sex, as this disease is mostly caused by sexual intercourse. If you have trichomoniasis throughout your pregnancy, it can be treated vaginally with metronidazole.
