<s>[INST] I am 30 weeks pregnant with my third child. I recently was treating a yeast infection and have now had vaginal pain that is becoming fairly severe to the point that it is constant and I cant even sleep. Im wondering if I need to go get checked with this pain in addition to the constant dull ache in my lower back and pelvic area. [/INST] Hello, Welcome to ChatDoctorAs you are having symptoms of fungal infection you need to be evaluated to confirm the presence of infection. Normally the yeast will be present in the genitals and kept under control by the helpful bacteria in the genitals, whenever there is a change in the environment this fungus will activate and produces the symptoms. As you are pregnant you need to consult your doctor at the earliest and confirm the diagnosis and take proper treatment otherwise it will have some deleterious effect on the outcome. Thank you. </s>
