All day sickness

Last Thursday we had seen our baby's heartbeat for the first time. It was truly an unforgettable moment, even though we still can't really associate ourselves to the baby's presence yet because it's still so tiny! (8mm) But I'm definitely feeling it through nausea since 4 weeks after conception. I thought I was doing pretty well before since I didn't experience any fatigue and was feeling pretty normal after BFP. By week 4, I was suddenly nauseous all day long, I even threw up a couple of times. I'm extremely sensitive to smells, all kinds of smells. I can't stand the fragrance from the body lotion which I've been using for years, I can't stand mom's cooking, especially anything with a strong aroma and I can smell anything from miles away. Everything tastes differently to me now which also means nothing tastes good anymore. I had to lay in bed most of the time because I also feel dizzy if I stay up for too long. I've been sleeping like a pig but eating like a chicken. I really don't like myself right now, I feel so useless and can't get myself up to do anything. Mom said this will probably last for a month or so before I start to feel a little better. I guess I shouldn't complain and should enjoy this special pregnancy moment. =) I just hope that I'll be getting enough nutrition for the baby by 2nd trimester. Everything we hope for is that the baby's healthy and normal. Can't wait for my first apt with my OB next week.
