Did you get an epidural during labor? If so, that will explain your headaches. If not, it can still be related to your hormones. I'm suffering with bad headaches every day, and I get occular migraines at least once or twice every two to three weeks. I've been having those kinds of migraines since I was 12 years old (I'm 27 now) but I would get one maybe once every few months to a year or so, which is in the normal range. Now it's constant and really affecting my vision. I did get an epidural in my last labor (only 3 weeks ago) so it could be that but then again, I was getting vision problems and headaches while I was still pregnant with her (which I know could be pregnancy related too). Best thing is for people like us who get headaches out of nowhere should be seen by our doctors who can send us to an eye doctor. My mom thinks I should see a neurologist because my vision is really bad even when I don't have a migraine.
