Period is 11 days late. taken 5 pregnancy tests. three were negative, 4th showed a very faint positive, 5th was a digital "not pregnant. am i pregnant

By the time: You are 11 days late on your cycle, the test lights up like a chritmas tree. The faint positive can be from the urine staying in the device or staring at it too hard. It does not sound ike u r pregnant. Missing a period for a month is not unusual. More than 3 months go in but it's generally easy to manage. Please consider the pill if not intending pregnancy. Good luck, have a good day.
