Question... For the past week or so I've been very sleepy to the point where I can't keep my eyes open 2 hours after I wake up. Also I've been putting mild sauce on some of my food and ive NEVER eatin mild sauce and sometimes when I wake up and even during the day my belly feels ehh. Kinda like when you haven't ate anything but I have. Makes me feel bleh could these be signs of pregnancy? Glow app says af due today but been starting on the 13 for past 3 months... Help
