For medicines, paracetamol is generally safe for fever or body ache, and simple cough syrups without strong drugs may be used, but avoid self-medicating with antibiotics or strong cold medicines. If symptoms are severe, persistent, or you have fever, consult your doctor to get pregnancy-safe treatment.

Breathing difficulty with severe cough and sneezing may be due to allergy, infection, or conditions like bronchitis or asthma.
