13 DAYS LATE MISSED PERIOD 😳😳

LAST PERIOD WAS MARCH 22, Last ONLY 3 days periods have been regular since then, NOT SURE WHAT HAS HAPPENED BEEN USING THE WITHDRAWAL METHOD? .. PERIOD WAS SUPPOSED TO START DAYS AGO TOOK 2 Test at 8days late negative THEN WENT TO pregnancy CENTER AT 10 negative 👎

Then ON DAY 11/12 I HAD BEEN FEELING NAUSEOUS THROWING UP all day long and feeling sickkk.

NOW IM 13 DAYS PAST AND HAVEN’T TESTED AGAIN WHAT SHOULD I DO ?

AM I PREGNANT OR AM I FREAKING OUT OVER NOTHING??
