Thanks for your query,based on the facts that you have posted it appears that you have severe vaginal infection
) which is perhaps the main cause of not conceiving.
Please consult qualified Gynaecologist for clinical and per speculum examination and get culture and sensitivity of the vaginal secretion done to find out the organisms causing this infection and antibiotics to which they are sensitive to.
In the mean while start taking antibiotics like Augmentin
twice daily and later on switch on to appropriate antibiotics as per culture report.
Wash your genitals and vagina with anti microbial solution like Betadine
