my periods are irregular, but the latest it’s ever been is 3 weeks EXACT. I’m now 38 days late & I’ve been sick for the past two weeks or so nauseous throwing up and all. my boobs feel fuller but they don’t hurt even my boyfriend said they’re looking rounder. these are telling signs I know, but the thing is, I took a pregnancy test when I was two weeks “late” (given my periods are irregular) and it said negative. please tell me if it could’ve been wrong. I feel so sick
