Please someone help me!!!!!!!!!

Okay so me and my husband have been TTC for two years now, and recently I found out that I might of been having a lot of chemical pregnancies. I never take a pregnancy test until a very late period because I don't want to get my hopes up. But a couple of months out of last year I noticed that I was a week or two late, I never took a pregnancy test though, so I noticed that my boobs got sore, my head hurt, and I felt nauseous, but at the end of the one or two weeks it would feel like something dropped in my stomach, or like someone was blowing air in my belly and then a day or two later I would start bleeding. I was just wondering if anybody else has experience this
