For me, it took me over 2 - 3 years to get pregnant once I had decided. Plus I went and saw many doctors (both western and Chinese) before I was pregnant. I even quit my job since the doc told me that I was too stressed to get pregnant. Did you see the family planning center to have body check for both you and your husband? This should be the first for you if you have decided to get pregnant.
Some people will try without the tests but wasn't successful. Then they go and see the doc. Since I am quite old in my age, I went to see family planning for check up before I started ML.
