Positive tests but I started my period on time

Katie • Wed, Mar 16

Every single one of these has a faint second line. All my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> said I’d start my period today but I thought nahhh these are all positive. This morning I woke up with my period. I just took a positive test a day ago. Is it possible I’m pregnant but my period still came this month? I just ovulated March 1st.
