Haih, jangan risau sangat lah! Demam dan batuk masa pregnant memang biasa dan dalam kebanyakan cases tak akan affect the baby, especially kalau it's just a common cold or mild flu. A few of us mums experienced the same thing around that stage, and our babies turned out fine, tapi because you're 6 months in, best you check with your doc to make sure it's nothing serious and maybe get a safe medication recommendation, okay?
