I'm going out of my mind!

Hi all, I'm going out of my mind I've done loads of pregnancy tests. I had what I thought was a period but I was on and off for 4 days at first it was heavy and then after a few hours just turned out light. My mood swings are unbearable I can be loving one minute and absolutely furious the next minute. I can't tolerate my other half even tho I love him dearly. My stomach is rock hard, my boobs are achy on and off I'm getting the pregnancy taste of a morning and really bad nausier. I'm obsessed with my house smelling and cleaning my house. I'm just loosing my mind. My only option is blood test but ya fitting it in around work and my daughter? Any ideas sorry for the long post but I'm so emotional xx
