HELPPP!!! CB ovulation test

Hi all so I have a question because I'm really confused now. The middle of last week on the 25 I started testing opk and didn't get my solid smiley until the 29th which I when I thought I ovulated. Now the days went by and yesterday the 3rd I started getting cramping again and I wasn't sure what was going on so this am it was still bothering me so I woke up with FMU and took both ovulation test and pregnancy test. The ovulation came back as a solid smiley... That means peak fertility and the pregnancy test came back negative. HELP!! what is going on?? Also glow predicted my fertile week to be right now and not last week of the 29th!! So confused right now
