gave him a handjob and he came a bit on his hand. he then wiped it off with an old tshirt a couple of minutes later and im pretty sure his hand was dry but i dont remember; and then around 2/3 minutes later he fingered me. this was a week ago and my period was due a couple days ago and never came, and ive been nauseous and dizzy which i read are things which could be signs of pregnancy within the first week. do you think there could be a chance i’m pregnant??
