Period 19 days late, feel dizzy sometimes, bloated, crampy, white water discharge - hpt are all negative. ?

Could be: Could be anovulatory cycle or irregular ovulation, these are the most common reasons (besides pregnancy) for a missed or late period.

Maybe anovulation?: If the HPT's are negative on multiple tries you may not really be pregnant....all the symptoms of the pie in the oven....but no pie! It happens. You've got 1 of 2 choices....get to a doctor where blood tests can be done which are generally a bit more sensitive plus an examination IN CASE....or just wait till your next period. If you come down...good to go....if not, time for appointment for sure
