For the past 2-3 weeks I have been nauseous all day along with being bloated, moody, my appetite is not the same, my sense of smell is enhanced and I have been absolutely tired all the time no matter how much sleep I get and my boobs feel fuller but I had what I believe to be a period it started heavy for the first bleed but then it got so light I didn't even need a pad or tampon and that went on for 2 days and now that I am off my monthly I am still having the symptoms. I took 3 pregnancy tests before my monthly and they all came out positive immediately the line was faint but it was blue and like I said it popped up immediately. I am just looking for some expert advice to help me out on knowing what's going on with my body. I mean I feel pregnant.

False positives are very rare. If you took three pregnancy tests correctly, and they all came back positive, then congrats, you're more than likely pregnant.
