I would be really, really uncomfortable with my family tracking, thinking or talking about my periods. That crosses a line for me. If they felt you had more symptoms around the time you have PMS they should just say that to you and let you monitor/manage it how you want to.

As far as your feeling off, hormones are evil things for bipolar women and I'm so glad that I don't have to deal with that so much anymore because it made things so much better when I didn't have a monthly internal trigger. So I'm sure it can be the cause of problems and I hope that it is something transient like that, even though I know it has to be scary waiting to see what happens.

I don't know if you need to call the dr or not; I think that only you know how you feel and if you should call now or wait a few more days to see while carefully monitoring and keeping your husband in the loop. I know that's a hard decision and I almost always let my dr know, just in case.
