You should be takeing zofran its safer than phenergan
My first pregnancy (in which I ended up miscarrying) my doctor tried me on phenergan and 2 other kinds of nausea pills. I honestly didn't like the way phenergan made me feel, all it did was put me to sleep and then when I woke up id be sick as a dog again. But with this pregnancy (I'm 33w+4d), for the first 5 months I couldn't eat or drink anything without it coming back up and I actually lost weight. I went to a different doctor and he put me on zofran which worked miracles on most days!
