I'm 15 w 3 days and I've been vomiting once a day. Usually around the same time each night. I often get nausea throughout the day. I didn't think much of it, just that I'm going to be one of the unlucky ladies who is sick the entire pregnancy. But this morning when I got dressed, I noticed my bra is not fitting. I have not had the greatest prenatal care. I switched providers because of that. My first appointment with the new OB is next Friday. I'm starting to get worried. Has anyone lost weight during their pregnancy and been okay?
