Hello, Trichomoniasis is a sexually transmitted disease. If symptoms do appear ( almost 70% of infected people do not have any signs or symptoms), they can include: vaginal itching, yellow or gray-green discharge, smelly and foamy discharge, redness of the genitals. An infection during pregnancy is associated with a higher risk of having a low-birth-weight baby and preterm birth. Trichomoniasis can be treated by antibiotic ( such as metronidazole ). Your partner should be treated as well. In my opinion You may suffer from trichomoniasis and You should contact Your doctor so he or she can check You and prescribe treatment. It is very important because You are pregnant. Hope I have answered your query. If you have any further questions I will be happy to help.
