what is going on with me?

I went to the doctors on 1/25 and I told them what was going on with me. ( I feel nauseous, I have to pee a lot, my period is late, I have word feeling in my stomach, and I have taken home pregnancy test and they come back negative and some don't even show up at all) they told me wait a week and take another and I waited two weeks. It came back negative ( home test). I have had three kids already and I have taken home test with all of them and they came back negative but when I go to the doctors to take one they come back positive. My husband goes not want me to go get a test done.  WhAt should I do?
