Pregnant? Or bad batch of tests?

So I am not sure when I ovulates last month as I had run out opks. We had sex a few times during what the app says was my fertile window. I tested the day my AF was due and thought I saw a squinted, which showed up inverted, but the AF showed up that night. Normally my cycle lasts 6-7 days with the first few days being very heavy then moderate bleeding to the end. This past period which ended a few days ago only lasted 4 days. 2 days were heavy then barely spitting for the last 2. I just got my pack of new pregnancy tests in. I have been feeling just bloated and heavy, and not like myself so I was like what the hell...I got a super thin line when inverted so I thought invalid so I texted again with same urine and this happened. This was around the 5 min mark... so I have a bad batch of tests?
