I'm 13 weeks and for the first 11 weeks I had nausea all day every day. But when I brushed my teeth in the morning I felt even worse. Sometimes even puking in the middle of brushing.(thank god my toilet is close to the sink!) now, I feel like every single time I brush my teeth I either have to try to mentally talk myself down from puking, or just puke because I can't help it. I feel fine before hand too. It's literally only when I brush my teeth..  It's getting to the point where I know it's gross, but I don't wanna brush my teeth. it's gotten so bad because when I puke, I puke so hard my face breaks out in red broken blood vessels all over and I feel as if I might pass out.
