Headaches and ovulation

Does anyone start catching headaches when ovulation approaches. I have been getting heachaches that coincide with my opks getting darker. Before seeing a line I'm fine but I've noticed that once I start to see them get darker I also have headaches at the same time. Could it be from the hormones building? I never really associated headaches with ovulation just pregnancy but I guess weirder things have happened.

I havent noticed myself ever having a head ache, but last time I ovulated (right before first ppaf) i was soooo nauseas and dizzy!! That is what made me take an hpt (bfn) and then an opk and it was a blaring positive! So a hormonal head ache would not surprise me at all.

Ok cuz it's the third day in a row that I have one. It don't last all day just more in the afternoon but that's also usually when I pick up my surge more too. I'm also nauseous like hell. So while i still have very light lines on my opks I know it isn't far off because my cervical mucus right now is very slippery so I know the EWCM is next. I'm actually getting more comfortable checking that stuff. My cervix is getting softer too. I checked that today
