I got sick a couple times right after we found out but I dont count it as really starting until about 6.5 weeks. At 6.5 weeks I started feeling sick and/or being sick almost every day sometimes 2 or 3 times. I thought it was letting up this week then I got sick about 7 times in one day on Wednesday. Then thursday felt better again but Early Friday morning (3am) I kept waking up thinking I was going to be sick and finally was several times when I got up for work. Even threw up water. I can't decide which is worse, throwing up a couple times almost every morning then being fine the rest of the day or throwing up all day twice a week but being fine the rest of the week. I just wish it would go away soon! ahha
