Thanks for your reply!

I do fill out the FMLA form whenever I am off for the PMDD/anxiety issue and it has been approved by HR.

I did speak with my manager, I think she understands a little more. I feel bad because I don't want to pick up extra hours now when I am dealing with the PMDD stuff, and she's asked me several times to come in extra. I emailed her and explained at this time I can't pick up extra hours because I have the medical issues going on.
