Hey ladies, how soon is too soon to take a pregnancy test!? I know the box says anything more than 5 days and the accuracy is way low... But I'm asking more personal experience. How long before your period has anyone here gotten a BFP? My period is in 9 days and I am just going crazy wanting to test! I am crampy, bloated, bachache-y, have a headache, nauseous, moody and my boobs hurt... But I often feel similar before AF, usually its not this soon before though. My PMS usually starts 3-4 days before, not 9! Just driving myself crazy, any advice/anicdotes appreciated!!! lol
