Wanting to get pregnant after miscarriage

Hi everyone just wanted some advice. I was pregnant back in October (only 6 weeks), this was my first pregnancy and I got pregnant right away. I had a miscarriage on Halloween. My doctor said it was most likely a chemical pregnancy. Either way it was devastating. I just got my period today (12/6/16) and my husband and I are planning on trying again in January. Just wanted some advice/suggestions for next time. Any would be great! Thanks in advance 😊
