Getting frequent headaches

So my head was hurting for 3 days and then I got my period. But these headaches were intense. I wasn’t dizzy or anything just had headaches I took some ibuprofen and felt fine. Now it’s been a week later I don’t have a headache but my head feels funny. Again, I’m not dizzy, unbalanced; or unsteady when I walk, just my head doesn’t feel all the way like it normally does. I was gonna go to imaging and get a scan but I am very scared. Although I am scared I rather find out what’s wrong with me. Can anyone give me any tips to advice?
