Okay so I'm confused. My period is so far 5 days late. I took 1 positive test (Walmart brand) 1 negative (first response) if my period really is coming this late. That means all of my fertile days were wrong right? I guess I should buy ovulation test instead of depending on this app. I'm really wanting to have a baby. And I'm not sure why I haven't gotten my period. I'm gonna wait a day before I test again.
