Hi Readytoheal,
Yes, the very same thing. I suffered from chronic migraine and was desperate to find anything to help. It went on for 6 1/2 years and towards the end I was seeing a dr. who tested my hormones and I was borderline slow thyroid. She wanted to put me on meds but I chose to wait. I'm the same age as you.
My cycle definitely was a trigger for my migraines and at that time I started spotting. I would get a really heavy flow, or it would come at odd times and be only spotty. It alarmed me to spot because I always had a regular period.
When I started the TMS approach the conditioning around my cycle and headaches was the strongest to break. It took a long time.
In the end, I think what helped what calming down my whole nervous system which took a lot of life changes and awareness. Over time, my period became regular again and migraines are down to one a month. What's interesting is if I take anti-anxiety meds when I feel PMS symptoms I can get through it with no migraines. Not paying attention to the calendar helped a lot too. It seems like the more attention you give it the more your brain will use it to get your attention.
Have you had any tests done for your hormones or anything else? You don't have to answer, but it's always best to rule out any problems. Chances are it's just TMS though.
Now, when I get my periods I get really bad cramps which hasn't happened since I was a teenager. I just try to chill out and ignore it. That will go away too, in time.
