Feeling Discouraged

Alyssa
We have officially been off birth control for 3 and a half years and have no results. I have temped and am ovulating, have regular periods, and have sex regularly. Some have told me to lay still after intercourse and some have said it doesn't matter either way. I'd like my boyfriend to get checked because I am wondering if it's not me that is the issue any more. We don't have money to consult with a doctor or get treatments and I honestly don't know what to do any more.
