I've had pain also, how ever I get them just before I would be having that TOM. Also for me it's lack of sleep. I'm not on any meds, just vit.
The hours of my days is some what off, I'm getting up at around 4:30 some days Monday's at 3:30, some days I do go back to bed.
If you feel you need to do go see you DR and see what they say.
Make sure you tell them when & were it's happening. And make sure they know about your cycle.
I was having issues with this over ten years ago, at that time i was Preg told the DR he said if it continues let me know, it did'ent.
But do let us know what you find out.
