You should do your test asap. All your symptoms sound like your pregnant. When my sister was pregnant, she said that she had this stretched feeling in her stomach quite early on and she couldn't stop peeing and she had morning sickness. She was never sick but just felt like she was going to be, and my mum had that as well when she was pregnant with us lot. I think you are. I'll keep my fingers crossed for you, although I don't think I need to as I think you are pregnant. Good luck xxx
