Can a person be charged for previous incidents before they were arrested in domestic violence cases?

My husband and I had been arguing loudly for a few days. On the day we stopped arguing the police came and said there were three 911 calls for domestic disturbance. We did not argue at all that day. When the police came, I freaked out because I had a warrant and I was also dead drunk. I gave a lot of false information pertaining to that day and I don't know why or what I said. My husband is currently incarcerated for multiple felony charges and facing 20 years they are saying. He is also tattooed from head to foot and looks like a total gang banger. He also has a history of violence and has three strikes. He has never hit me in the six years we have been married. The police said that he looks like the "type". He is definitely being discriminated against in more than one way. What can I do?
