Hi this is my first time posting, I'm aftwr some advice if possible. I'm 11 days late for AF which is not normal for me. With both of my PP I tested positive really early, but I've done 6 real cheap tests (pharmace twin pack day of missed AF) and a 5 pack from Amazon with pretty bad reviews for false results. All 6 have come up negative...am I just not pregnant or should I invest in better tests? I'm usually like clockwork on a 28 day cycle. I know it's not stress because I'm always stressed and it doesn't effect AF lol
