My period is 9 days late, my appetite has increased, i wake up early in the mornings (around 3am) feeling hungry, i am so tired can fall asleep quickly. The hpt come back negative the most recent one came back invalid. I have a few symptoms like I did when I was preg the 1st time which is hair loss. My moods have been a roller coaster last week and this week so far. I had a headache yesterday and today my vision seems to be a little blury. Could I be preg or just completely stressed out?
