Chronic Endometritis

After 2 MC's I insisted on doing tests as most Gynies only raise concern after 3. I am 36 and I dont want to wait for the 3rs one before I know a reason. 
So results show its Chronic Endometritis and I now on 100mg Doxycyl for 10 days. 
Anyone have a similar experience and what are my chances of carrying a baby to full term. I have been asking so many questions but all I get is drink the meds and try again! Maybe I should switch to another Doctor!
