I am 8 dpo (according to glow, 7 according to Ovia). Ever since Sunday (today is Tuesday) I have been feeling like crap! Headache (head feels like it is constantly shrinking), stuffy nose, stomach feels tight. I wouldn't say cramps, just kind of like almost a tugging feeling. My breasts are only sensitive to the touch on the sides. No clue if these are pregnancy symptoms or I'm just sick. I know it's too early to test for sure. I just need some insight!
