I have been pregnant already twice in the last 8 months and lost both so I know what I feel like when I am . I pretty sure i know when I ovulated but you never know ? Thanks for the advise
If you are really due on Tuesday, the hpts should show it by now. But if you aren't tracking your ovulation, it's possible that you ovulated later and therefore your period is due later...if you still have no period by Thursday, test again.
WIshing you the best...
Out of curiousity, why are you 'pretty positive'?
