How?!

Af is 8 days late as of this morning. No sign she’s coming. Continuous signs of pregnancy since about 2 days before she was supposed to arrive. Af was due Sept. 24th. Crampy, lower back pain, a cold that came out of no where (no one around me is sick), acne coming up consistently, and having to pee more frequently. Took 2 tests last night which both came out negative, pic taken 3 mins after test, and the single test taken this morning, pic taken 3 mins after test. How?!
