M.K.
i don't pay very close attention to my cycle, but it was about time for my period, and then i had pretty strong pms (but nothing extraordinary, except my boobs felt really hot in addition to achy). almost a week later, when my period still hadn't arrived, took a test (absolutely did not expect to be pregnant) and yep! i had even joked with my husband that santa was bringing my period for christmas (the really icky cramps and hot boobs were on christmas eve), but nope, i got something way better! if you're really regular and are 2 days late, i'd probably encourage you to take the test (but i'm impatient like that). :)
