I need some help

Okay soo I currently use 2 different <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a>.

Well I took a test a week before my period (first photo below) I got a faint positive. July 25 2019 (story continued below)

Second photo below was taken on Saturday July 27 2019 ( again faint line)

Well I was going to wait to see if AF would show well this morning I’m supposed to start & got this sorry tmi (story continued below)

Normally my periods are heavy & my periods have been light this past couple times ... me & my boyfriend kinda do it a lot both my apps are logged when we done it (posted below)

So my question is could I still be pregnant? Could this be implantation bleeding ? It doesn’t seem like it’s getting heavier but I’m still going to make an appointment with my ob bc I know everyone & every pregnancy is different I just really need some advice.
