Thanks for posting your query.
You can cough up a streak of blood if the coughing is very strenuous. Dry cough
can be due to many causes, including viral infections and may sometimes also be a manifestation of asthma
It may not be anything to worry about, but because you are pregnant, I would suggest you see your doctor straight away. Your doctor will examine you and maybe order some tests to make sure it is nothing serious. As the baby is moving well, it is a sign that the baby is happy inside the womb. The kicks are normal at this stage.
