 [ Symptoms ] i am pregnant in my first trimester and i have some chest congestion is there any safe medications i can use [ Disease ] hi this seems to be a result of eczema and dry skin tendancy that ur body has doesnt seem to be a vaginal infection for sure sex causes friction on the affected skin and mucosa causing the superficial layers of skin to get washed off this causes inner layers of skin to get exposed causing itching after having sex try using moisturisers and olive oil thanks
