About to return to work after a year of maternity leave, using accrued holiday to take me to my return to work date next week. Going back into a new department with a new boss. Had an early positive pregnancy test a few weeks ago, but have had spotting since, and my pink dye tests have shown little progression, so was prepared for a miscarriage. Am bleeding quite heavily since last night, so am assuming the worst. Compassionate leave policy includes time off for miscarriage, but this would involve telling my new boss I was pregnancy and am now miscarrying, and not sure quite how to communicate this! WWYD?
