Is using ur fmu that important? I took a test recently that was negative...still no af, and the spotting once a day with mild cramps is still happening. And ive noticed i only cramp when im really hungry (if that makes any difference) when i took the test, it was later in the afternoon. Per glow i was supposed to start on the 17th....i dunno i wanna stop thinking about this lol but i cant. Ive never had any of these things happen before and my period runs like clock work (since like the 7th grade). And ive been super nauseous this morning, so bad so that i tried to make myself throw up but nothing came up, which again never happens...wth is wrong with me!!
