Any insight... Freaking out!

Supposed to get my period today, sexually active practice pull out method, has been very effective for over a year. But my period didn't come today, and earlier this month I noticed a few familiar symptoms from my first pregnancy. Clear blue digital test says not pregnant, first response 5day early test has faint 2nd line.... Anyone else had this problem and did it end up as positive or negative? Will re-test in a couple days if period doesn't come
