I’m late🤦🏽‍♀️

so my period is pretty predictable, I cramp, spot and then it’ll be here. However, I’ve only cramped for about 2 days and nothing happened. I’ve been feeling nauseous, bloated, constipated and I really think I could be pregnant.. Not to mention my period is 3 days late according to my tracker. I am under a lot of stress because of finals and school but that has never played a part before. Is it too soon to tell if I am pregnant? i’m really nervous lol
