I have a really bad cough. Theses cough drops arent doing much for me especially at night. What medicine can I take for this while im pregnant?

Several. The Robitussin products are safe. If the cough is being caused by allergies, Claritin (loratadine) may also help. A humidifier by your bed at night is useful.
See your doctor. The most important first step is to see your doctor. You could have an infection, such as pneumonia or bronchitis. You could also have asthma, or other important-to-detect conditions.
