So before I started birth control when I was 16, my period were irregular. Once I stopped taking birth control at age 21 (and now 22), my period was coming every month and a half. Then out of nowhere, my periods went from 7days long to only 1-3days long (average of 2 days) but coming at the same time every month (give or take a day or two). Now I'm a week late.... My period was supposed to start 23 June. I took a test 21 June and it was negative. It's hard to decipher wether I'm having period symptoms or early pregnancy symptoms. Should I take another test or is my period just late?
