Cause for concern?

Yesterday I had 3 BFPs from three different tests, a Clearblue digital, rapid, and a faint line on a pregmate strip. Today’s pregmate strip was even more faint, hardly even noticeable, but my clear blue rapid was darker. I didn’t do a digital since the rapid was so obvious. Cause for concern or just wait a few days? Only about 12 DPO and first pregnancy.
