Am I finally pregnant?

I tested this morning with FMU. I thought it was going to say negative so I layed back down. When I got tup to be again I saw the faintest of faint - yet distinguishable lines. I flipped is this it? My BFP. This line wasnt like an evaporation line it was way faint but still pink. I even broke the test open to get a closer look. It's a pink positive. I tested again, it wasn't FMU this time... negative. Just one pink negative. My have been occasionally sore, and are getting visibly bigger. I have pressure in my abdomen/pelvic region. I was having pains in my left ovarian region. I'm tired, moody, unusually happy at times... I've been having heartburn and horrible gas pressure. I just dunno! My period was due the 24th. This is the first test to have a hint of being a BFP! I've been feeling odd since. A mixture of confusion and joy. I don't know what to think.
