I'm 8 weeks, 3 days pregnant today. My first ultrasound was two weeks ago, and I heard the baby's heartbeat, and they said the baby was growing good. I was having breast pains, back pains, and minor cramping, like a normal pregnancy, and I just don't feel it anymore, I get sick every few days & if I smell something that doesn't agree with me or eat something that doesn't agree with my stomach, and I'm dizzy just as much as when I found out I was pregnant, but my breast pains are going away, coming back every once in a while, and I haven't been as achy/crampy anymore. I haven't had any signs of a miscarriage, like bad cramps or bleeding or anything, should I still be worried?
