breast tenderness, which are not as bad as when my period usually is about to start, BUT my nipples are very sensitive. more hungry then usual, fatigue. yesterday i had an headache all day, and pricking feelings in my lower abdomen, today it’s just tight. mouth is continuously dry, even after i drink water it gets dry again immediately, especially throughout the night. what do you guys think? could i be overthinking it or possible pregnancy?
