Disappointed in myself!!!!

Ashley
Hey my name is Ashley. I am the proud mother of 2 beautiful girls and the proud step mother of a very handsome boy. My husband and I have our children from previous relationships but we don't have a child together. We have been trying for 3 years to have a baby. Our results are always the same. Negative on every test. I have given up on the idea of having a baby. He hasn't yet. Now it seems like a job with the same end results. I just don't know what to do anymore. I want a baby with him. I have gotten one positive test one time but unfortunately it was in fact a false positive. The Dr told me that is what it was. What do we do. Could really use some helpful advice
