so i noticed probably two days ago that i could be laying in bed and EVERY TIME i get up , i would get lightheaded & it would feel like i’m about to black out ( the feeling before you black out ) or like i’ve been spinning & a circle & just stopped . along with other differences i don’t feel like typing bc it’s early , was that anyone else’s sign of pregnancy? AF is estimated to come in 5 days & i don’t wanna test & get a negative that actually winds up positive..
