I am always hungry and thirsty, but if I eat to fast or eat a big meal on an empty stomache I feel nauseated, so bad that I need to lie down. Sometimes I get nauseated and a hot flash will appear. Yesterday, I felt like I ate so much that I should have popped but I still went to bed feeling hungry. I have also experienced mild headaches and I have been forgetting things easily. I have also gone to bed exceptionally early due to the fact that I was tired. I looked up symptoms like mine online (just curiosity) and most said early signs of pregnancy I have irregular periods but have been trying to track it, me and my husband have had sexual intercourse everyday since we have gotten married, give or take a day. Could I be pregnant? Or is there something else that I should be worried about?
