I had a dream two weeks ago that I was pregnant, and I forgot about it. Since last week, I've been feeling nauseous. On Thursday past, I felt really bad, I threw up, and my husband was with me, and the little one was sitting next to us (and from that moment on, I've been feeling nauseous in the morning and in the evening when I go to bed). I started looking at my belly ? laughing at myself ? I probably just gained weight. Although the scales say I weigh 45. I feel nauseous regardless of what I eat. I visited my parents for two days. And it felt like a fish was throwing up near my pubic area
