Hi Pfhanson28
Depends where you were in menopause when you started HRT. Had you gone 12 months (looks like maybe 11?) without a natural period before starting? If not then you are still likely peri-menopausal in which case you can experience irregular bleeding due to your natural cycle (HRT does not shut down ovulation).
Also what type and dose of HRT are you taking? Sounds like continuous combined if you are surprised by a bleed. Normally, bleeding after 7 months without on a conti HRT should probably be investigated but it is most likely to be normal variation - your natural cycle, and potentially an imbalance between oestrogen and progestogen, depending on the product. The really sore boobs tend to suggest your natural cycle, if you haven't experienced this at other times since starting HRT.
