well i got my 1st headache when i was 18 and ill be 25 in about a week so i've had for about 7 years now...i believe i started my cycle last week of may and i would get hit everyday and they were very painful...now i get them every 2 day and the pain is not that bad..does that mean my cycle is ending???

No way of telling, sorry. Some people have rigidly fixed cycles, others which never fall into a pattern. Just no test or signs to tell us.

Some say their "shadows" are a signal for them; others mention a fog-like feeling, something like a light cloth resting on our heads, which signal a change coming.

But not worth fretting about it--as long as you have a good treatment plan ready to put into action.

Mauricio,
Like the posts before, no actual way of telling.  I am one of the lucky ones in that I get hit only every 4 years.  Had my last cycle last May.  I have had them for about 23 years now.  I started a log over the past two cycles to see if there was any similarities.  I don't know how often you get them but a log may be helpful for the future something you can refer back to.  Sometimes they just stop, but the last cycle I had shadows linger for about a month with no pain greater than a 1 or a 2 then they finally went away.

Hope this helps.  But I can tell you there are plenty of good people on this site willing to help and answer whatever questions they can.
