Im so lost

I started glow this month past mid cycle. It was af was to arrive the 28th of this month. So I decided to go back through and add my days I recorded in ovia. Now it's pushed my fertility week up and now says it just ended a day ago instead of last week. We bd the original week and have only bd once this week during the new calculated week. I'm so upset. Why did it recalculate it!!! My tww was almost over, and now I have to wait til June to test??!! I am so upset and confused :((
