I seem to have thrush but i also have lower tummy pain, blood stained discharge and my left ovary is hurting especially when i cough?

Go for major dx: A UTI can cause lower and discomfort and may be part of the picture. The discharge may be incidental but there is a chance you have an infection of the uterus. Thrush is an oral candida infection and likely not related to this but i think u need to get seen. I place my bet on a uti, but not there to examine so don't give it too much weight. Also, do a upt.
