Having a D&C done for the 3rd time.

Hi everyone my husband and I have been trying for 3yrs to have a baby. With this being said it hasn't been a easy process after seeing a fertility doctor and doing Nemours of test we found out I have endometriosis and PCOS. I never in my life thought it would be this hard to fall pregnant it definitely has been an emotional rollercoaster. After being on Clomid and tracking my ovulation nothing has happened. So my doctor is going to clean me out good again and start me on metformin and Clomid to see if that will work. Please if everyone could send lots of baby dust and prayers my way.
