So, I never miss a period. Ever.  So this month I was due for mine on the 26th (according to glow, it normally comes between the 18th-23rd) and it didnt show up. I have been incredibly hungry, peeing more often (have also been drinking more water though), had nipple discharge (has never happened before), but no nausea. I took a test yesterday night (1/29/16) and it was negative. I have been told it's better to do in the morning so I tried this morning and messed the test up. I was just hoping you guys could weigh in and see what I should do. Thanks.
