So...I've been having these headaches all of the time, I'm nauseous (not throwing up just its always sort of in the background) with stomach bloating (by the way what's with the bloating???), my lower back is always aching, I can smell certain things really sensitively but others not so much, my nipples are kind of itchy (sorry for the tmi) but my breasts aren't sore, I'm really tired..I can stay awake but I'm just not really all that full of energy. Is this what pregnancy is like? Or is this something totally different and just happening while I'm pregnant?
