Hello and welcome to HCM,
At the offset let me tell you that your innocence is endearing.
Headache can be caused by a variety of causes and not just pregnancy
. But since you described a periodic headache that narrows our diagnosis.
You can assume it to be just a sinus headache
and start a course of antibiotic like the amoxycillin-clavulanate
625 for five days along with a pain killer like paracetamol
after food. Your doctor will know about these.
Also do steam inhalation and take only warm fluids.
If you do not get better then you need to take a CT of the brain and the sinuses
and get back to me with the reports
get well soon and do not worry
