First symptoms of pregnancy??

Please don’t judge i’m still young and pretty terrified. I went out with a guy a little bit back and it ended up just being a one night stand, he decided he didn’t wanna respond to my texts anymore and I believe i’m blocked. I’ve been feeling pretty bloated and i’m waiting for my cycle to start up but i’ve started craving foods I haven’t eaten in years. Also could just me getting over a cold but certain smells are making me nauseous and i’m hyper-sensitive to smells. My parents will kick me out if I end up being pregnant and I have no where to go now that we’re in the middle of a move.

Just wondering what early signs would be and if I should be worried!
