Period day late. Confusing pregnany tests.

Chelsea

So my period is one day late. I'm always on time. I've had insane symptoms. So I've been testing for 3 days. I saw a line on a cheapie, then I took a digital and it malfunctioned with a "?" And an hour later said "yes+" then this morning I have the faintest line in history on frer. I don't even think you'll be able to see the line on the pictures I'm going to post. When I was pregnant with my son my lines progressively got darker by the day before I even miss my period. Could I still be pregnant? I'd appreciate thoughts on my tests too. I'm so confused!

First two tests were yesterday. Last test was this morning (day of expected period)
