Suggest Treatment For Headache

I have a constant forehead headache/pressure and sometimes behind my eyes. I do not have blurred vision or spots but i just notice it. I would get occasional tension headaches while pregnant and before pregnancy but after the birth of my son two months ago i started on Progestin BC a couple weeks ago and noticed they were more frequent and pretty much all day long. It does not wake me up but more of an annoyance. What could it be?
