Our expert says:
The cause for your headaches is not clear, but pregnancy does cause nasal congestion due to hormonal changes. An ENT examination will be helpful to exclude a nasal cause, but this is very rare.
You should check with your Gynae first, but it may be helpful to use your nasal spray twice daily, with two sprays in each nostril (this comes to eight sprays ). In this dose, no systemic absorbtion occurs, but you should first check this with your doctor.
