I have to agree with Lori, we can't really assess if this is normal healthy/unhealthy for you.
It's really about whether or not you feel it's right. I would say though that considering you get migrains etc when you get the spotting that it would probably be a good idea to go to the gyno and get it checked out.
I hope it isn't anything too bad, except the weirdness that is TOM and it's cycles.
