Ttc advice anyone?

Okay ladies, I have been TTC for over a year now, but not really seriously. Meaning I haven't gone to a doctor about it. My boyfriend and I have been trying for a while but sometimes we are busy with work and things and don't have sex on the ovulation days. What are some things you guys did to get pregnant? Is there any vitamins or supplements you took? Anything you did or didn't do? Is there certain food or drink you ate while TTC? Any advice helps!
